15.3 Operation

Timer RC has the following operating modes.

• Timer mode operation

Enables output compare and input capture functions by setting the IOA2 to IOA0 and IOB2 to

IOB0 bits in TRCIOR0 and the IOC3 to IOC0 and IOD3 to IOD0 bits in TRCIOR1.

• PWM mode operation

Enables PWM mode operation by setting the PWMD, PWMC, and PWMB bits in TRCMR.

• PWM2 mode operation

Enables PWM2 mode operation by setting the PWM2 bit in TRCMR.

The FTIOA to FTIOD pins indicate the timer output mode by each register setting. Set 1 to the

PMCR and PMR bits corresponding to the pins selected by the PMC.
