Output Peripheral Event
the increase event will decrease the duty cycle value and decrease event will increase the duty
cycle value. If both the increase event and the decrease event occur at the same time for a
channel, the duty cycle value will not be changed.
The number of channels supporting input peripheral events is device specific. Please refer to the
Module Configuration section at the end of this chapter for details.
The PWMA also supports one output peripheral event (event_ch0) to the Peripheral Event Sys-
tem. This output peripheral event is connected to channel 0 and will be asserted when the
timebase counter reaches the duty cycle value for channel 0. This output event is always
enabled.
