• P24/PO4-A/TIOCA4-A/TMO0-A/RxD4-A
The pin function is switched as shown below according to the combination of the TPU channel
4 settings (by bits MD3 to MD0 in TMDR_4 of the TPU, bits IOA3 to IOA0 in TIOR_4, and
bits CCLR1 and CCLR0 in TCR_4), bits OS3 to OS0 in TCSR_0 of the 8-bit timer, bit
NDER4 in NDERL of the PPG, bit RE in SCR_4 of the SCI, bits PPGS, TPUS, TMRS in
PFCR3, bit RXD4S in PFCR4 and bit P24DDR.
