Notes: 1. IRQ5-B input when the ITS5 bit in ITSR is 1.
2. TIOCB4-B input when MD3 to MD0 = B'0000 or B'01xx and IOB3 to IOB0 = B'10xx.
3. When using as PO5-B output, set PPGS in PFCR3 to 1 before other register setting.
4. When using as TIOCB4-B input/output, set TPUS in PFCR3 to 1 before other register
setting.
5. When using as TMO1-B output, set TMRS in PFCR3 to 1 before other register setting.
