Access:
• CHIDx: Counter Event on Channel x
0 = No new counter event has occurred since the last read of the PWM_ISR1 register.
1 = At least one counter event has occurred since the last read of the PWM_ISR1 register.
• FCHIDx: Fault Protection Trigger on Channel x
0 = No new trigger of the fault protection since the last read of the PWM_ISR1 register.
1 = At least one trigger of the fault protection since the last read of the PWM_ISR1 register.
