(3) Port mode registers 1 and 2 (PM1, PM2)
Cautions 1. Set the pin set to analog input to the input mode by using port mode register 1 (PM1).
When using AMP0-/ANI0/P20, AMP0OUT/PGAIN/ANI1/P21, and AMP0+/ANI2/P22 pins for the operational
amplifier 0, set PM20 to PM22 to 1.
When using AMP1-/ANI8/P10, AMP1OUT/ANI9/P11, and AMP1+/ANI10/P12 pins for the operational amplifier 1,
set PM10 to PM12 to 1.
The output latches of P20 to P22 and P10 to P12 at this time may be 0 or 1.
If PM20 to PM22 and PM10 to PM12 are set to 0, they cannot be used as the operational amplifier 0 and 1 pins.
PM1 and PM2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to FFH.
