The pin function is switched as shown below according to the combination of the operating
mode, bit EXPE, bit WAITE in BCR of the bus controller, 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*
PPGS, TPUS, and TMRS in PFCR3, bit WAITS in PFCR4, and bit P25DDR.
2. PO5-A output when the PPGS bit in PFCR3 is 0.
3. TIOCB4-A input/output when the TPUS bit in PFCR3 is 0.
4. TMO1-A output when the TMRS bit in PFCR3 is 0.
5. WAIT-B input when the WAITS bit in PFCR4 is 1.
