If regis ‘1’, then the contents of Main Duty Cycle register (OCxR) is read. If regis ‘0’, then the contents of Secondary Duty Cycle register (OCxRS) is read. Return Value: If regis ‘1’, then the contents of Main Duty Cycle register (OCxR) is read. If regis ‘0’, then the contents of Secondary Duty Cycle register (OCxRS) is read. If Output Compare module is in PWM mode, ‘-1’ is returned. Remarks: The read of Duty Cycle registerhappens only when Output Compare module is not in PWM mode. Else, a value of ‘-1’ is returned.
