Notes: 1. TIOCA2 input when MD3 to MD0 = B'0000 or B'01xx and IOA3 = 1.
2. TIOCB2 output disabled.
3. When using as SSCK0-A input, set SSCK0S1 and SSCK0S0 in PFCR5 to B'00 before
other register setting.
4. When using as SSCK0-A output, set SSCK0S1 and SSCK0S0 in PFCR5 to B'00 before
other register setting.
5. P16DDR = 0 when the SSU pin is used as input.
6. Do not set up for SSU unless SSCK0S1 and SSCK0S0 = B'00 in PFCR5.
Use as I/O port, TPU or EXDMAC pin.
