Pulse-Width Modulator for Motor Control
9.7.2 Software Output Disable
9.7.3 Output Port Control
Technical Data
168
The function of the fault control and event bits is the same as in
automatic mode except that the PWMs are not re-enabled until the
FFLAGx event bit is cleared by writing to the FTACKx bit and the filtered
fault condition is cleared (logic low).
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
interrupt request, and there are no event flags associated with the PWM
disable bits.
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.
