• P26/PO6/TIOCA5/SDA2/ADTRG1
The pin function is switched as shown below according to the combination of the TPU channel
5 settings (by bits MD3 to MD0 in TMDR_5, bits IOA3 to IOA0 in TIOR_5, and bits CCLR1
and CCLR0 in TCR_5), bit NDER6 in NDERL of PPG, bits TRGS1, TRGS0, and EXTRGS in
ADCR_1 of ADC, bit ICE in ICCRA_2 of I
2
C, and bit P26DDR.

Notes: 1. TIOCA5 input when MD3 to MD0 = B'0000 or B'01xx and IOA3 = 1.
2. TIOCB5 output disabled.
3. ADTRG1 input when EXTRGS = 0 and TRGS1 = TRGS0 = 1.
4. NMOS open-drain output regardless of P26ODR.
