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 IOC3 to IOC0 in TIORL_3, and bits CCLR2
to CCLR0 in TCR_3), bit NDER2 in NDERL of the PPG, bits PPGS, TPUS, and TMRS in
PFCR3, and bit P22DDR.
2. TIOCD3 output disabled. Output disabled and settings (2) effective when BFA = 1 or
3. PO2-A output when the PPGS bit in PFCR3 is 0.
4. TIOCC3-A input/output when the TPUS bit in PFCR3 is 0.
5. TMCI0-A input when the TMRS bit in PFCR3 is 0.
BFB = 1 in TMDR_3.
