function
When the TIOCD0/TCLKBS bit in PTCNT2 is cleared to 0, this pin can be used as the
TIOCD0/TCLKB pin.
According to operating modes, the TPU channel 0 settings by 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 P23DDR bit, pin functions change as follows.
