25.4.2 Register Descriptions
The address of a register is the sum of a base address and an address offset. The base address is defined at
the core level and the address offset is defined at the module level. There are a set of registers for each
PWM submodule, for the configuration logic, and for each Fault channel.
25.4.3 Submodule Registers
These registers are repeated for each PWM submodule. The base address of submodule 0 is the same as
the base address for the PWM module as a whole. The base address of submodule 1 is $50. This is the
base address of the PWM module plus an offset based on the number of registers in a submodule. The
base address of submodule 2 is equal to the base address of submodule 1 plus this same offset.
