Starting two timers synchronously with the master enable MTO signal trigger
▄
Configure PWM0 to operate in the master mode to send its enable signal as a trigger output
(MMSEL = 0x1).
▄
Enable the PWM0 master timer synchronization function by setting the TSE bit in the MDCFR
register to 1 to synchronize the slave timer.
▄
Configure PWM1 to receive its input trigger source from the PWM0 trigger output (TRSEL = 0x9).
▄
Configure PWM1 to be in the slave trigger mode (SMSEL = 0x6).
▄
Set "1" to the PWM1 TME bit.
▄
Start PWM0 by writing '1' to the TME bit.

Trigger Peripherals Start

To interconnect to the peripherals, such as ADC, Timer and so on, the PWM could output the MTO
signal or the channel compare match output signal CHxOREF (x = 0 ~ 3) to be used as peripherals
input trigger signal, depending on the MCU specification.
