Memory Map and Register Definition
This section describes in detail all the registers and register bits in the PWM module.
The special-purpose registers and register bit functions that are not normally available to device end users,
such as factory test control registers and reserved registers, are clearly identified by means of shading the
appropriate portions of address maps and register diagrams. Notes explaining the reasons for restricting
access to the registers and functions are also explained in the individual register descriptions.

Module Memory Map
This section describes the content of the registers in the PWM module. The base address of the PWM
module is determined at the MCU level when the MCU is defined. The register decode map is fixed and
begins at the first address of the module address offset. The figure below shows the registers associated
