7.3.4
P2PCR controls the on or off state of input pull-up MOSs for port 2.
7.3.5
When the corresponding bit in PTCNT2 is cleared to 0, port 2 pins can be used as TPU I/O pins.
The relationship between register setting values and pin functions is as follows.

Pin function
When the TIOCB2/TCLKDS bit in PTCNT2 is cleared to 0, this pin can be used as the
TIOCB2/TCLKD pin.
According to operating modes, the TPU channel 2 settings by the MD3 to MD0 bits in
TMDR_2, the IOB3 to IOB0 bits in TIOR_2, and the CCLR1 and CCLR0 bits in TCR_2, and
the combination of the TPSC2 to TPSC0 bits in TCR_0, the TIOCB2/TCLKDS bit, and the
P27DDR bit, pin functions change as follows.

In normal extended and single-chip modes
When the pins are in the input states, the
corresponding input pull-up MOS is turned on
when a P2PCR bit is set to 1.
In multiplex extended mode
Operation is not affected.
