12.6.11 Auxiliary PWM Event Output Control Register y
- The event signal is stretched using the peripheral clock because different APGs may be operating from different clock sources. The leading edge of the event pulse is produced in the clock domain of the APWM Generator. The trailing edge of the stretched event pulse is produced in the peripheral clock domain.
- No event will be produced if the selected APWM Generator is not present.
- This is the APWM Generator output signal prior to Output mode logic and any output override logic.
- This signal should be the APGx_clk domain signal prior to any synchronization into the system clock domain.
- ‘y’ denotes a common instance (A-F).
