Output function
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 IOD3 to IOD0 in TIORL_3, and bits
CCLR2 to CCLR0 in TCR_3), bit NDER3 in NDERL of the PPG, bit TE in SCR_4 of the SCI,
bits PPGS, TPUS, and TMRS in PFCR3, bit TXD4S in PFCR4, and bit P23DDR.
2. PO3-A output when the PPGS bit in PFCR3 is 0.
3. TIOCD3-A input/output when the TPUS bit in PFCR3 is 0.
4. TMCI1-A input when the TMRS bit in PFCR3 is 0.
5. TxD4-A output when the TXD4S bit in PFCR4 is 0.
