The reset state of each individual bit is listed within the register description section (see
“Memory Map and Registers,”
modes which are initialized during or just following reset are described within this section.

The PWM8B4C module interrupt is disabled when PWM5ENA is clear.
“PWM Shutdown Register (PWMSDN).”

The 8-bit up/down counter is configured as an up counter out of reset.
All the channels are disabled and all the counters don’t count.
