10.6.4 Pin Functions
Port 6 pins also function as 8-bit timer I/Os, interrupt inputs, and DMAC I/Os. The
correspondence between the register specification and the pin functions is shown below.
• P65/TMO1/DACK1/IRQ13
The pin function is switched as shown below according to the combination of bit DMACS in
PFCR2, bit SAE1 in DMABCRH, bits OS3 to OS0 in TCSR_1 of the 8-bit timer, bit P65DDR,
and bit ITS13 in ITSR.

and bit ITS12 in ITSR.
