The pin function is switched as shown below according to the combination of bit TEE0 in
DMATCR of the DMAC, bit TMRS in PFCR3, bit P62DDR, and bit ITS10 in ITSR of the
interrupt controller.
The pin function is switched as shown below according to the combination of bit TMRS in
PFCR3, bit P61DDR, and bit ITS9 in ITSR of the interrupt controller.
