• P20/PO0-A/TIOCA3-A/TMRI0-A/PUPD+
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 TIOR H_3, and bits
CCLR2 to CCLR0 in TCR_3), bit NDER0 in NDERL of the PPG, bit PULLUP_E in CTLR of
the USB, bits PPGS, TPUS and TMRS in PFCR3, and bit P20DDR.
