1 (count starts) is written to the TSTART bit in the TRCMR register.
A trigger is input to the TRCTRG pin
The TRCIOB pin outputs the initial level in accordance with the value of the TOB
bit in the TRCCR1 register. The TRC register retains the value before count stops.
The TRCIOB pin outputs the initial level. The TRC register retains the value before
count stops if the CCLR bit in the TRCCR1 register is set to 0. The TRC register is
set to 0000h if the CCLR bit in the TRCCR1 register is set to 1.
The edge or edges of the signal input to the TRCTRG pin can be used as the
PWM output trigger: rising edge, falling edge, or both rising and falling edges
