Port C

(1) PC7/WUE15/TIOCB2/TCLKD
The pin function is switched as shown below according to the combination of the register setting
of the TPU and the PC7DDR bit. When the WUEMR15 bit in WUEMR of the interrupt controller
is cleared to 0, this pin can be used as the WUE15 input pin.
This pin functions as the TCLKD input when TPSC2 to TPSC0 in TCR_0 is B'111. Also, when
channel 2 is set to phase counting mode, this pin functions as the TCLKD input. This pin functions
as TIOCB2 input when TPU channel 2 timer operating mode is set to normal operation or phase
counting mode and IOB3 in TIOR_2 is set to 1.
