In MCAN mode, the static TR consists of the following information.
Param | PSIL Addr | Field | Description |
---|---|---|---|
Burst | 0x400 | 31 | When set, enables VBUSP burst mode on this channel. See the MCAN burst description for more information. |
Acc32 | 0x400 | 30 | Not used |
X | 0x400 | 26:24 | Not used |
Y | 0x400 | 11:0 | Buffer Size. This field specifies how many bytes should be read from an MCAN RX buffer. This field includes the 8 byte MCAN header on the initial packet fragment. A buffer size less than 16 is treated as 16, and a buffer size greater than 72 is treated as 72. |
EOL | 0x401 | 31 | EOL Mode. Normally, when the Z count of FIFO operations has been reached, the PDMA will close the packet with an 'EOP' indication. When this flag is set, the PDMA will instead trigger an EOL at the completion of Z. |
Z | 0x401 | 23:0 | Buffer Count. This field specifies how many MCAN RX buffers should be read before closing the CPPI packet with an 'EOP' indication. When this count is greater than 1, multiple MCAN RX buffers will be read into a single CPPI packet buffer. The 8 byte MCAN header will be skipped on subsequent MCAN buffer reads. Setting this field to NULL will suppress all packet delineation, and should be avoided. |
