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 IOB3 to IOB0 in TIOR_2, and bits CCLR1
and CCLR0 in TCR_2), bits TPSC2 to TPSC0 in TCR_0 and TCR_5, bit NDER15 in NDERH
of PPG, bits MSS, CSS1, and CSS0 in SSCRH and bit SSUMS in SSCRL of SSU, bits
SCS0S1 and SCS0S0 in PFCR5, and bit P17DDR.

2. TCLKD input when the setting for either TCR_0 or TCR_5 is TPSC2 to TPSC0 = B'111.
3. SCS0-A input when SCS0S1 and SCS0S0 = B'00 in PFCR5, and SSUMS, MSS, CSS1,
4. SCS0-A output when SCS0S1 and SCS0S0 = B'00 in PFCR5, and SSUMS, MSS,
TCLKD input when channels 2 and 4 are set to phase counting mode.
and CSS0 = B'00××, B'0101, or B'0110. Do not set up for TPU output with SCS0-A
input.
CSS1, and CSS0 = B'011×.
