Pin Functions

Port 2 pins also function as PPG outputs*, TPU I/Os, and TMR I/Os. The correspondence between
the register specification and the pin functions is shown below.
Note: * Not supported by the H8S/2366.

/TIOCB5
The pin function is switched as shown below according to the combination of the TPU channel
5 settings (by bits MD3 to MD0 in TMDR_5, bits IOB3 to IOB0 in TIOR_5, and bits CCLR1
and CCLR0 in TCR_5), bit NDER7*
