OUTCTL— Output Control Enable Bit

This read/write bit allows the user to manually control the PWM pins. When set, the PWM generator is no longer the input to the dead-time and output circuitry. The OUTx bits determine the state of the PWM pins. Setting the OUTCTL bit does not disable the PWM generator. The generator continues to run, but is no longer the input to the PWM dead-time and output circuitry. When OUTCTL is cleared, the outputs of the PWM generator immediately become the inputs to the dead-time and output circuitry.

1 = PWM outputs controlled manually

0 = PWM outputs determined by PWM generator

OUT6–OUT1— PWM Pin Output Control Bits

These read/write bits control the PWM pins according to Table 12-10.
