Note
The function of the P20/ANI0/AMP0-, P21/ANI1/AMP0O, P22/ANI2/AMP0+, P23/ANI3/AMP1-,
P24/ANI4/AMP1O, P25/ANI5/AMP1+, P26/ANI6 pins can be selected by using the A/D port configuration
register (ADPC), port mode register 2 (PM2), analog input channel specification register (ADS), and
operational amplifier control register (OAC). Refer to 4.2.3 Port 2.
