7.5 Resets
All PWM registers are reset to their default values upon any system reset.
The reset forces all registers to their reset states and tri-states the PWM outputs.
7.6 Interrupts
Each of the submodules within the eFlexPWM module can generate an interrupt from
several sources. The fault logic can also generate interrupts. The interrupt service routine
(ISR) must check the related interrupt enables and interrupt flags to determine the actual
cause of the interrupt.
