Legend:
×: Don’t care
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 IOB3 to IOB0 in TIORH_3, and bits
CCLR2 to CCLR0 in TCR_3), bit NDER1 in NDERL of the PPG, bit TE in SCR_3 of the SCI,
bits PPGS, TPUS, and TMRS in PFCR3, and bit P81DDR.
2. TIOCB3-B input/output when the TPUS bit in PFCR3 is 1.
3. TMRI1-B input when the TMRS bit in PFCR3 is 1.
