Pin function
Notes: 1. IRQ1-B input when the ITS1 bit in ITSR is 1.
The pin function is switched as shown below according to the combination of bit ETENDE in
EDMDR_2 of EXDMAC, bit P82DDR, and bit ITS2 in ITSR of the interrupt controller.
The pin function is switched as shown below according to the combination of bit TE in SCR_3
of SCI, TPU channel 3 settings (by bits MD3 to MD0 in TMDR_3, bits IOB3 to IOB0 in
TIORH_3, and bits CCLR2 to CCLR0 in TCR_3), bit NDER1 in NDERL of PPG, bits PPGS,
TPUS, and TMRS in PFCR3, bit P81DDR, and bit ITS1 in ITSR of the interrupt controller.

2. PO1-B output when the PPGS bit in PFCR3 is 1.
3. TIOCB3-B input/output when the TPUS bit in PFCR3 is 1.
4. TMRI1-B input when the TMRS bit in PFCR3 is 1.
IRQ2-B input when the ITS2 bit in ITSR is 1.
