Section 10 I/O Ports
10.6.4
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.

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.

* IRQ13 interrupt input when ITS13 = 0.
* IRQ12 interrupt input when ITS12 = 0.
