• P60/IRQ8-A/DREQ0/TMRI0-A
The pin function is switched as shown below according to the combination of bit TMRS in
PFCR3, bit P60DDR, and bit ITS8 in ITSR of the interrupt controller.
P60DDR 0 1
P60 input P60 output

Notes: 1. When used as the counter reset input pin for the TMR, both the CCLR1 and CCLR0 bits
in TCR_0 should be set to 1.
2. IRQ8-A input when the ITS8 bit in ITSR is 0.
3. When using as TMRI0-A input, set TMRS in PFCR3 to 0 before other register setting.
