Pulse Width Modulator for Motor Control (PWMMC)
9.6.5 Output Port Control
Technical Data
158
Conditions may arise in which the PWM pins need to be individually
controlled. This is made possible by the PWM output control register
(PWMOUT) shown in
If the OUTCTL bit is set, the PWM pins can be controlled by the OUTx
bits. These bits behave according to
When OUTCTL is set, the polarity options TOPPOL and BOTPOL will
still affect the outputs. In addition, if complementary operation is in use,
the PWM pairs will not be allowed to be active simultaneously, and dead-
time will still not be violated. When OUTCTL is set and complimentary
operation is in use, the odd OUTx bits are inputs to the dead-time
generators as shown in
