Bit Descriptions:
• Registers are named using mixed upper and lower case alphanumeric, for example,
(An example register description is shown below. This description is used for the following
examples.)
A specific bit may be specified in one of three ways:
Hexidecimal numbers are referred to as 0x0000_0000.
Binary numbers are referred to as 0000_0000b.
1. Register name[bit number], for example, SysCfg[29]
2. Register name.bit field[bit number], for example, SysCfg.REV[1]
3. Register name.bit field[bit name], for example, SysCfg.SBOOT
Note:

CAUTION:In the Internal Register Map in
SysCfg or PxDDR. Where there are multiple registers with the same names, a lower case
“x” is used as a place holder. For example, in the PxDDR registers, x represents a letter
from A to H, indicating the specific port being discussed
REV
