Notes: 1. TIOCA4-B input when MD3 to MD0 = B'0000 or B'01xx and IOA3 to IOA0 = B'10xx.
2. IRQ2-A input when the ITS2 bit in ITSR is 0.
3. TIOCB4-B output disabled.
4. When using as PO4-B output, set PPGS in PFCR3 to 1 before other register setting.
5. When using as TIOCA4-B input/output, set TPUS in PFCR3 to 1 before other register
setting.
6. When using as TMO0-B output, set TMRS in PFCR3 to 1 before other register setting.
