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 SAE1 in
DMABCRH of the DMAC, bits OS3 to OS0 in TCSR_1 of the 8-bit timer, bit P65DDR, and
bit ITS13 in ITSR.
SAE1 0 1
OS3 to OS0 All 0 Not

Note: * IRQ13 interrupt input when ITS13 = 0.
• P64/TMO0/DACK0/IRQ12
The pin function is switched as shown below according to the combination of bit SAE0 in
DMABCRH of the DMAC, bits OS3 to OS0 in TCSR_0 of the 8-bit timer, bit P64DDR, and
bit ITS12 in ITSR.
