Pulse-Width Modulator for Motor Control (PWMMC)
DT2 — Dead-Time 2 Bit
DT1 — Dead-Time 1 Bit
12.9.11 PWM Output Control Register
The PWM output control register (PWMOUT) is used to manually control the PWM pins.
OUTCTL— Output Control Enable Bit
OUT6–OUT1— PWM Pin Output Control Bits

Current sensing pin IS1 is monitored immediately before dead-time ends due to the assertion of
PWM2.
Current sensing pin IS1 is monitored immediately before dead-time ends due to the assertion of
PWM1.
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.
These read/write bits control the PWM pins according to
1 = PWM outputs controlled manually
0 = PWM outputs determined by PWM generator
