DMAC Port Error Raw Status
This register provides the actual status of individual port errors. It also indicates which channel is serviced by an external AHB port (which is frozen by a port error). A port error aborts operations on all serviced channels (channel enable bit is forced to 0) and prevents further transfers via that port until the error is cleared by writing to the DMASWRESET register.

KEYWRITEAREA is shown in Figure 13-19 and described in Table 13-63.

Return to the Summary Table.

Key Store Write Area
This register defines where the keys should be written in the key store RAM. After writing this register, the key store module is ready to receive the keys through a DMA operation. In case the key data transfer triggered an error in the key store, the error will be available in the interrupt status register after the DMA is finished. The key store write-error is asserted when the programmed/selected area is not completely written. This error is also asserted when the DMA operation writes to ram areas that are not selected.
The key store RAM is divided into 8 areas of 128 bits.
192-bit keys written in the key store RAM should start on boundaries of 256 bits. This means that writing a 192-bit key to the key store RAM must be done by writing 256 bits of data with the 64 most-significant bits set to 0. These bits are ignored by the AES engine.

Key Store Written Area
This register shows which areas of the key store RAM contain valid written keys.
When a new key needs to be written to the key store, on a location that is already occupied by a valid key, this key area must be cleared first. This can be done by writing this register before the new key is written to the key store memory.
Attempting to write to a key area that already contains a valid key is not allowed and results in an error.

Used for regular non-ECB modes (CBC/CTR):
-[127:0] - AES_IV - For regular AES operations (CBC and CTR) these registers must be written with a new 128-bit IV. After an operation, these registers contain the latest 128-bit result IV, generated by the EIP-120t. If CTR mode is selected, this value is incremented with 0x1: After first use - When a new data block is submitted to the engine
For GCM:
-[127:0] - AES_IV - For GCM operations, these registers must be written with a new 128-bit IV.
After an operation, these registers contain the updated 128-bit result IV, generated by the EIP-120t. Note that bits [127:96] of the IV represent the initial counter value (which is 1 for GCM) and must therefore be initialized to 0x01000000. This value is incremented with 0x1: After first use - When a new data block is submitted to the engine.
For CCM:
-[127:0] - A0: For CCM this field must be written with value A0, this value is the concatenation of: A0-flags (5-bits of 0 and 3-bits 'L'), Nonce and counter value. 'L' must be a copy from the 'L' value of the AES_CTRL register. This 'L' indicates the width of the Nonce and counter. The loaded counter must be initialized to 0. The total width of A0 is 128-bit.
For CBC-MAC:

AES Crypto Length 0 (LSW)
These registers are used to write the Length values to the EIP-120t. While processing, the length values decrement to 0. If both lengths are 0, the data stream is finished and a new context is requested. For basic AES modes (ECB, CBC, and CTR), a crypto length of 0 can be written if multiple streams need to be processed with the same key. Writing 0 length results in continued data requests until a new context is written. For the other modes (CBC-MAC, GCM, and CCM) no (new) data requests are done if the length decrements to or equals 0.
It is advised to write a new length per packet. If the length registers decrement to 0, no new data is processed until a new context or length value is written.
When writing a new mode without writing the length registers, the length register values from the previous context is reused.

31-0C_LENGTHW0hC_LENGTH[31:0]
Bits [60:0] of the crypto length registers (LSW and MSW) store the cryptographic data length in bytes for all modes. Once processing with this context is started, this length decrements to 0. Data lengths up to (261: 1) bytes are allowed.
For GCM, any value up to 236 - 32 bytes can be used. This is because a 32-bit counter mode is used
the maximum number of 128-bit blocks is 232 - 2, resulting in a maximum number of bytes of 236 - 32.
A write to this register triggers the engine to start using this context. This is valid for all modes except GCM and CCM.
Note: For the combined modes (GCM and CCM), this length does not include the authentication only data
the authentication length is specified in the AESAUTHLEN register
All modes must have a length greater than 0. For the combined modes, it is allowed to have one of the lengths equal to 0.
For the basic encryption modes (ECB, CBC, and CTR) it is allowed to program zero to the length field
in that case the length is assumed infinite.
All data must be byte (8-bit) aligned for stream cipher modes
bit aligned data streams are not supported by the EIP-120t. For block cipher modes, the data length must be programmed in multiples of the block cipher size, 16 bytes.
For a host read operation, these registers return all-0s.

If both lengths are 0, the data stream is finished and a new context is requested. For basic AES modes (ECB, CBC, and CTR), a crypto length of 0 can be written if multiple streams need to be processed with the same key. Writing 0 length results in continued data requests until a new context is written. For the other modes (CBC-MAC, GCM and CCM) no (new) data requests are done if the length decrements to or equals 0.
It is advised to write a new length per packet. If the length registers decrement to 0, no new data is processed until a new context or length value is written.
When writing a new mode without writing the length registers, the length register values from the previous context is reused.

Bits [60:0] of the crypto length registers (LSW and MSW) store the cryptographic data length in bytes for all modes. Once processing with this context is started, this length decrements to 0. Data lengths up to (261: 1) bytes are allowed.
For GCM, any value up to 236 - 32 bytes can be used. This is because a 32-bit counter mode is used
the maximum number of 128-bit blocks is 232 - 2, resulting in a maximum number of bytes of 236 - 32.
A write to this register triggers the engine to start using this context. This is valid for all modes except GCM and CCM.
Note: For the combined modes (GCM and CCM), this length does not include the authentication only data
the authentication length is specified in the AESAUTHLEN register
All modes must have a length greater than 0. For the combined modes, it is allowed to have one of the lengths equal to 0.
For the basic encryption modes (ECB, CBC, and CTR) it is allowed to program zero to the length field
in that case the length is assumed infinite.
All data must be byte (8-bit) aligned for stream cipher modes
bit aligned data streams are not supported by the EIP-120t. For block cipher modes, the data length must be programmed in multiples of the block cipher size, 16 bytes.
For a host read operation, these registers return all-0s.

The data registers are typically accessed through the DMA and not with host writes and/or reads. However, for debugging purposes the data input/output registers can be accessed via host write and read operations. The registers are used to buffer the input/output data blocks to/from the EIP-120t.
Note: The data input buffer (AES_DATA_IN_n) and data output buffer (AES_DATA_OUT_n) are mapped to the same address locations.
Writes (both DMA and host) to these addresses load the Input Buffer while reads pull from the Output Buffer. Therefore, for write access, the data input buffer is written
for read access, the data output buffer is read. The data input buffer must be written before starting an operation. The data output buffer contains valid data on completion of an operation. Therefore, any 128-bit data block can be split over multiple 32-bit word transfers
these can be mixed with other host transfers over the external interface.

These registers must be written with the 512-bit input data. The data lines are connected directly to the data input of the hash module and hence into the engine's internal data buffer. Writing to each of the registers triggers a corresponding 32-bit write enable to the internal buffer.
Note: The host may only write the input data buffer when the rfd_in bit of the HASH_IO_BUF_CTRL register is high. If the rfd_in bit is 0, the engine is busy with processing. During processing, it is not allowed to write new input data.
For message lengths larger than 64 bytes, multiple blocks of data are written to this input buffer using a handshake through flags of the HASH_IO_BUF_CTRL register. All blocks except the last are required to be 512 bits in size. If the last block is not 512 bits long, only the least significant bits of data must be written, but they must be padded with 0s to the next 32-bit boundary.
Host read operations from these register addresses return 0s.

7PAD_DMA_MESSAGER/W0hNote: This bit must only be used when data is supplied through the DMA. It should not be used when data is supplied through the slave interface.
This bit indicates whether the hash engine has to pad the message, received through the DMA and finalize the hash.
When set to 1, the hash engine pads the last block using the programmed length. After padding, the final hash result is calculated.
When set to 0, the hash engine treats the last written block as block-size aligned and calculates the intermediate digest.
This bit is automatically cleared when the last DMA data block is arrived in the hash engine.
6GET_DIGESTR/W0hNote: The bit description below is only applicable when data is sent through the slave interface. This bit must be set to 0 when data is received through the DMA.
This bit indicates whether the hash engine should provide the hash digest.
When provided simultaneously with data_in_av, the hash digest is provided after processing the data that is currently in the HASHDATAINn register. When provided without data_in_av, the current internal digest buffer value is copied to the HASHDIGESTn registers.
The host must write a 1 to this bit to make the intermediate hash digest available.
Writing 0 to this bit has no effect.
This bit is automatically cleared (that is, reads 0) when the hash engine has processed the contents of the HASHDATAINn register. In the period between this bit is set by the host and the actual HASHDATAINn processing, this bit reads 1.
5PAD_MESSAGER/W0hNote: The bit description below is only applicable when data is sent through the slave interface. This bit must be set to 0 when data is received through the DMA.
This bit indicates that the HASHDATAINn registers hold the last data of the message and hash padding must be applied.
The host must write this bit to 1 in order to indicate to the hash engine that the HASHDATAINn register currently holds the last data of the message. When pad_message is set to 1, the hash engine will add padding bits to the data currently in the HASHDATAINn register.
When the last message block is smaller than 512 bits, the pad_message bit must be set to 1 together with the data_in_av bit.
When the last message block is equal to 512 bits, pad_message may be set together with data_in_av. In this case the pad_message bit may also be set after the last data block has been written to the hash engine (so when the rfd_in bit has become 1 again after writing the last data block).
Writing 0 to this bit has no effect.
This bit is automatically cleared (i.e. reads 0) by the hash engine. This bit reads 1 between the time it was set by the host and the hash engine interpreted its value.
4-3RESERVEDR/W0hWrite 0s and ignore on reading
2RFD_INR/W1hNote: The bit description below is only applicable when data is sent through the slave interface. This bit can be ignored when data is received through the DMA.
Read-only status of the input buffer of the hash engine.
When 1, the input buffer of the hash engine can accept new data
the HASHDATAINn registers can safely be populated with new data.
When 0, the input buffer of the hash engine is processing the data that is currently in HASHDATAINn
writing new data to these registers is not allowed.
1DATA_IN_AVR/W0hNote: The bit description below is only applicable when data is sent through the slave interface. This bit must be set to 0 when data is received through the DMA.
This bit indicates that the HASHDATAINn registers contain new input data for processing.
The host must write a 1 to this bit to start processing the data in HASHDATAINn
the hash engine will process the new data as soon as it is ready for it (rfd_in bit is 1).
Writing 0 to this bit has no effect.
This bit is automatically cleared (i.e. reads as 0) when the hash engine starts processing the HASHDATAINn contents. This bit reads 1 between the time it was set by the host and the hash engine actually starts processing the input data block.
0OUTPUT_FULLR/W0hIndicates that the output buffer registers (HASHDIGESTn) are available for reading by the host.
When this bit reads 0, the output buffer registers are released
the hash engine is allowed to write new data to it. In this case, the registers should not be read by the host.
When this bit reads 1, the hash engine has stored the result of the latest hash operation in the output buffer registers. As long as this bit reads 1, the host may read output buffer registers and the hash engine is prevented from writing new data to the output buffer.
After retrieving the hash result data from the output buffer, the host must write a 1 to this bit to clear it. This makes the digest output buffer available for the hash engine to store new hash results.
Writing 0 to this bit has no effect.
Note: If this bit is asserted (1) no new operation should be started before the digest is retrieved from the hash engine and this bit is cleared (0).

For hash operations that do not require finalization (input data length is multiple of 512-bits which is SHA-256 data block size), the length field does not need to be programmed since not used by the operation.
If the message length in bits is below (232-1), then only this register needs to be written. The hardware automatically sets HASH_LENGTH_IN_H to 0s in this case.
The host may write the length register at any time during the hash session when the HASHIOBUFCTRL.RFD_IN is high. The length register must be written before the last data of the active hash session is written into the hash engine.
host read operations from these register locations will return 0s.
Note: When getting data from DMA, this register must be programmed before DMA is programmed to start.

0SW_RESETR/W0hIf this bit is set to 1, the following modules are reset:
- Master control internal state is reset. That includes interrupt, error status register, and result available interrupt generation FSM.
- Key store module state is reset. That includes clearing the written area flags
therefore, the keys must be reloaded to the key store module.
Writing 0 has no effect.
The bit is self cleared after executing the reset.
