When the corresponding bit in PTCNT2 is set to 1, port 8 pins can be used as TPU I/O pins
(ExTIOCB0 and ExTIOCA0). The relationship between register setting values and pin functions is
as follows.

Output function
When the TIOCB0S bit in PTCNT2 is set to 1, this pin can be used as an ExTIOCB0 pin.
The pin function is switched as shown below according to the combination of the TPU channel
0 settings by the MD3 to MD0 bits in TMDR_0 and the IOB3 to IOB0 bits in TIORH_0, the
TIOCB0S bit, and the P87DDR bit.
When the TRGS1 and TRGS0 bits in ADCR are all set to 1, this pin functions as an ADTRG
input pin.
* When TIOCB0S = 1, MD3 to MD0 = B'0000, and IOB3 to IOB0 = B'10xx, this pin
