with the PWM and their relative offset from the base address. The register detail description follows the
order they appear in the register map.
Reserved bits within a register will always read as 0 and the write will be unimplemented. Unimplemented
functions are indicated by shading the bit. .
NOTE
Register Address = Base A Address Offset, where the Base Address
is defined at the MCU level and the Address Offset is defined at the module
level.
