The following table lists the conventions used in this document.
| Notation | Meaning |
|---|---|
| General Register Notation | |
| REGISTER | APB registers are indicated in uppercase bold. For example, PBORCTL is the Power-On and Brown-Out Reset Control register. If a register name contains a lowercase n, it represents more than one register. For example, SRCRn represents any (or all) of the three Software Reset Control registers: SRCR0, SRCR1, and SRCR2. |
| bit | A single bit in a register. |
| bit field | Two or more consecutive and related bits. |
| offset 0xnnn | A hexadecimal increment to a register address, relative to that module base address as specified in Table 1-15. |
| RESERVED | Register bits marked RESERVED are reserved for future use. In most cases, reserved bits are set to 0; however, user software should not rely on the value of a reserved bit. To provide software compatibility with future products, the value of a reserved bit should be preserved across a read-modify-write operation. |
| yy:xx | The range of register bits inclusive from xx to yy. For example, 31:15 means bits 15 to 31 in that register. |
| Register Bit Field Reset Value | This value in the register bit diagram shows the bit field value after any reset, unless noted. |
| 0 | Bit cleared to 0 on chip reset |
| 1 | Bit set to 1 on chip reset |
| X | Nondeterministic |
| Pin and Signal Notation | |
| [ ] | Pin alternate function; a pin defaults to the signal without the brackets. |
| pin | Refers to the physical connection on the package. |
| signal | Refers to the electrical signal encoding of a pin. |
| assert a signal | Change the value of the signal from the logically false state to the logically true state. For active-high signals, the asserted signal value is 1 (high); for active-low signals, the asserted signal value is 0 (low). The active polarity (high or low) is defined by the signal name (see SIGNAL and SIGNAL below). |
| deassert a signal | Change the value of the signal from the logically true state to the logically false state. |
| SIGNAL | Signal names are in uppercase. An overbar on a signal name indicates that it is active-low. To assert SIGNAL is to drive it low; to deassert SIGNAL is to drive it high. |
| SIGNAL | Signal names are in uppercase. An active-high signal has no overbar. To assert SIGNAL is to drive it high; to deassert SIGNAL is to drive it low. |
| Numbers | |
| X | An uppercase X indicates any of several values is allowed, where X can be any legal pattern. For example, a binary value of 0X00 can be either 0100 or 0000, a hex value of 0xX is 0x0 or 0x1, and so on. |
| 0x | Hexadecimal numbers have a prefix of 0x. For example, 0x00FF is the hexadecimal number FF. All other numbers within register tables are assumed to be binary. Within conceptual information, binary numbers are indicated with a b suffix, for example, 1011b, and decimal numbers are written without a prefix or suffix. |
