• Manufacturer: Renesas Electronics Corporation.

• P64/IRQ12-A/DACK0/TMO0-A
SAE0
OS3 to OS0
P64DDR
Pin function
Notes: 1. IRQ12-A input when the ITS12 bit in ITSR is 0.
• P63/IRQ11-A/TEND1/TMCI1-A

P63DDR
Pin function
Notes: 1. IRQ11-A input when the ITS11 bit in ITSR is 0.
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 TMRS in
PFCR3, bit P64DDR, and bit ITS12 in ITSR of the interrupt controller.
The pin function is switched as shown below according to the combination of bit TEE1 in
DMATCR of the DMAC, bit TMRS in PFCR3, bit P63DDR, and bit ITS11 in ITSR of the
interrupt controller.
2. TMO0-A output when the TMRS bit in PFCR3 is 0.
