Section 10 I/O Ports
10.6.4
P6ODR specifies the output type of each port 6 pin.
10.6.5
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 TMRS in
PFCR3, bit P65DDR, and bit ITS13 in ITSR of the interrupt controller.

IRQ13-A interrupt input*
Description
Reserved
These bits are always read as 0. Only the initial
values should be written to these bits.
Setting a P6ODR bit to 1 makes the corresponding
pin an NMOS open-drain output pin, while clearing
a P6ODR bit to 0 makes the corresponding pin a
CMOS output pin.
