9.3.1
This section describes the content of the registers in the scalable PWM module. The base address of the
scalable 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 with the scalable 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.
9.3.2
This section describes in detail all the registers and register bits in the scalable PWM module.
