The pin function is switched as shown below according to the combination of the TPU channel
2 settings (by bits MD3 to MD0 in TMDR_2, bits IOA3 to IOA0 in TIOR_2, and bits CCLR1
and CCLR0 in TCR_2), bit NDER14 in NDERH of PPG, bits MSS and SCKS in SSCRH and
bit SSUMS in SSCRL of SSU, bits SSCK0S1 and SSCK0S0 in PFCR5, and bit P16DDR.
2. TIOCB2 output disabled.
3. SSCK0-A input when SSCK0S1 and SSCK0S0 = B'00 in PFCR5, and SSUMS, MSS,
4. SSCK0-A output when SSCK0S1 and SSCK0S0 = B'00 in PFCR5, and SSUMS, MSS,
and SCKS = B'001 or B'101. Do not set up for TPU output with SSCK0-A input.
and SCKS = B'×11.
