RM0046 FlexPWM
Doc ID 16912 Rev 5 701/936
The PWM generator uses the last values loaded if RUN is cleared and then set while LDOK
equals zero.
When the RUN bit is cleared:
● The RF flag and pending CPU interrupt requests are not cleared
● All fault circuitry remains active
● Software/external output control remains active
● Deadtime insertion continues during software/external output control
25.10 Clocks
25.11 Interrupts
Each of the submodules within the PWM can generate an interrupt from several sources.
The fault logic can also generate interrupts. The interrupt service routine (ISR) must check
the related interrupt enables and interrupt flags to determine the actual cause of the
interrupt.
