Port C

(1) PC7/WUE15/TIOCB2/TCLKD
The pin function is switched as shown below according to the combination of the TPU channel 2
setting, the TPSC2 to TPSC0 bits in TCR_0 of TPU, and the PC7DDR bit.
When the WUEMR15 bit in WUEMR of the interrupt controller is cleared to 0, this pin functions
as the WUE15 input pin.
TPU channel 2 setting
PC7DDR
Pin function
Notes: 1. This pin functions as the TCLKD input pin when the TPSC2 to TPSC0 bits in TCR_0
are B'111. Also, when channel 2 is set to phase counting mode, this pin functions as the
TCLKD input pin.
2. This pin functions as the TIOCB2 input pin when the TPU channel 2 timer is set to
normal operation mode, or to phase counting mode while the IOB3 bit in TIOR_2 is set
to 1.
(2) PC6/WUE14/TIOCA2
The pin function is switched as shown below according to the combination of the TPU channel 2
setting and the PC6DDR bit.
When the WUEMR14 bit in WUEMR of the interrupt controller is cleared to 0, this pin functions
as the WUE14 input pin.
TPU channel 2 setting
PC6DDR
Pin function
Note: * This pin functions as the TIOCA2 input pin when the TPU channel 2 timer is set to
normal operation mode, or to phase counting mode while the IOA3 bit in TIOR_2 is set
to 1.
