×: Don’t care
Notes: 1. TIOCA3-A input when MD3 to MD0 = B'0000 and IOA3 to IOA0 = B'10××.
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 IOA3 to IOA0 in TIORH_3, and bits
CCLR2 to CCLR0 in TCR_3), bit NDER0 in NDERL of PPG, bit PULLUP_E in DMA of
USB, bit P20DDR, and bit ITS8 in ITSR of the interrupt controller.
P20/PO0-A/TIOCA3-A/IRQ8-B*
2. IRQ8-B input when the ITS8 bit in ITSR is 1.
3. TIOCB3 output disabled.
4. PO0-A output when the PPGS bit in PFCR3 is 0.
5. TIOCA3-A input/output when the TPUS bit in PFCR3 is 0.
