16-bit Motor Control PWM - Overriding Complementary Pairs
Overriding the PWM is accomplished by using the PWM output control and output override logic. The PWM Output Override feature is controlled by the IOCON register. The OVRDAT bits of IOCONx determine the state of the PWM I/O pins when the output is overridden by OVRENH or OVRENL.
The dead time generator is with overrides. Dead times are calculated and inserted when the PWM channels are overridden manually.
Please read "Section 14.12.1 PWM Output Override Logic" of the High-Speed PWM FRM.
