28.10 EC-Only Registers
The registers listed in the EC-Only Register Summary table are for a single instance of the Blinking/Breathing PWM.
The addresses of each register listed in this table are defined as a relative offset to the host “Base Address” defined in
the EC-Only Register Base Address Table.
