×: Don’t care
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, bits IOB3 to IOB0 in TIOR_4, and bits CCLR1
and CCLR0 in TCR_4), bits OS3 to OS0 in TCSR_1 of the 8-bit timer, bit NDER5 in NDERL
of PPG, bit C/A in SMR_3 and bits CKE0 and CKE1 in SCR_3 of SCI, bits PPGS, TPUS, and
TMRS in PFCR3, and bit P85DDR.
