The reset state of each individual bit is listed within the register description section (see
“Memory Map and Register Definition,”
functions or modes which are initialized during or just following reset are described within this section.
12.6
The PWM8B6CV1 module has only one interrupt which is generated at the time of emergency shutdown,
if the corresponding enable bit (PWMIE) is set. This bit is the enable for the interrupt. The interrupt flag
PWMIF is set whenever the input level of the PWM5 channel changes while PWM5ENA=1 or when
PWMENA is being asserted while the level at PWM5 is active.

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.
