The pin function is switched as shown below according to the combination of the TPU channel
3 settings (by bits MD3 to MD0 in TMDR_3, bits IOD3 to IOD0 in TIORL_3, and bits
CCLR2 to CCLR0 in TCR_3), bit NDER3 in NDERL of the PPG, bit RE in SCR_3 of the
SCI, bits PPGS, TPUS, and TMRS in PFCR3, and bit P83DDR.
2. TIOCD3-B input/output when the TPUS bit in PFCR3 is 1.
3. TMCI1-B input when the TMRS bit in PFCR3 is 1.
