Pin function
When the TIOCB1/TCLKCS bit in PTCNT2 is set to 1, this pin can be used as the
ExTIOCB1/ExTCLKC pin.
According to operating modes, the TPU channel 1 settings by the LWROE bit, the MD3 to
MD0 bits in TMDR_1, the IOB3 to IOB0 bits in TIOR_1, and the CCLR1 and CCLR0 bits in
TCR_1, and the combination of the TPSC2 to TPSC0 bits in TCR_0 and TCR_2, the
TIOCB1/TCLKCS bit, and the P90DDR bit, the pin function is switched as shown below.
