12.6.2 Software Output Disable
Setting PWM disable bit DISX or DISY in PWM control register 1 immediately disables the corresponding
PWM pins as determined by the bank and disable mapping register. The PWM pin(s) remain disabled
until the PWM disable bit is cleared and a new PWM cycle begins as shown in
Figure
12-31. Setting a
PWM disable bit does not latch a CPU interrupt request, and there are no event flags associated with the
PWM disable bits.
12.6.3 Output Port Control
When operating the PWMs using the OUTx bits (OUTCTL = 1), fault protection applies as described in
this section. Due to the absence of periodic PWM cycles, fault conditions are cleared upon each CPU
cycle and the PWM outputs are re-enabled, provided all fault clearing conditions are satisfied.
