When the corresponding bit in PTCNT2 is set to 1, port 9 pins can be used as TPU I/O pins
(ExTIOCD0/ExTCLKB, ExTIOCB2/ExTCLKD, ExTIOCA2, and ExTIOCB1/ExTCLKC). The
relationship between register setting values and pin functions is as follows.
• P97/WAIT/ExTIOCD0/ExTCLKB
• Extended Mode (EXPE = 1)
• Single-Chip Mode (EXPE = 0)

When the TIOCD0/TCLKBS bit in PTCNT2 is set to 1, this pin can be used as the
ExTIOCD0/ExTCLKB pin.
According to operating modes, the TPU channel 0 settings by the WMSn1 (n = 3 to 1) bit in
BCRAn, the MD3 to MD0 bits in TMDR_0, the IOD3 to IOD0 bits in TIORL_0, and the
CCLR2 to CCLR0 bits in TCR_0, and the combination of the TPSC2 to TPSC0 bits in TCR_0
to TCR_2, the TIOCD0/TCLKBS bit, and the P97DDR bit, the pin function is switched as
shown below.
