Section 8 I/O Ports
(5) PC3/WUE11/TIOCD0/TCLKB
The pin function is switched as shown below according to the combination of the TPU channel 0
setting, the TPSC2 to TPSC0 bits in any of TCR_0 to TCR_2 of TPU, and the PC3DDR bit.
When the WUEMR11 bit in WUEMRA of the interrupt controller is cleared to 0, this pin
functions as the WUE11 input pin.

WUE11 input pin/TCLKB input pin*¹
Notes: 1. This pin functions as the TCLKB input pin when the TPSC2 to TPSC0 bits in any of
TCR_0 to TCR_2 are B'101. Also, when channel 0 is set to phase counting mode, this
pin functions as the TCLKB input pin.
2. This pin functions as the TIOCD0 input pin when the TPU channel 0 timer is set to
normal operation mode, or to phase counting mode while the IOD3 to IOD0 bits in
TIOR_0 are set to B'10xx. (x: Don't care)
(6) PC2/WUE10/TIOCC0/TCLKA
The pin function is switched as shown below according to the combination of the TPU channel 0
setting, the TPSC2 to TPSC0 bits in any of TCR_0 to TCR_2 of TPU, and the PC2DDR bit.
When the WUEMR10 bit in WUEMRA of the interrupt controller is cleared to 0, this pin
functions as the WUE10 input pin.

Notes: 1. This pin functions as the TCLKA input pin when the TPSC2 to TPSC0 bits in any of
TCR_0 to TCR_2 are B'100. Also, when channel 0 is set to phase counting mode, this
pin functions as the TCLKA input pin.
2. This pin functions as the TIOCC0 input pin when the TPU channel 0 timer is set to
normal operation mode, or to phase counting mode while the IOC3 to IOC0 bits in
TIOR_0 are set to B'10xx. (x: Don't care)
