<1> Set bit 5 (ADCEN) of peripheral enable register 0 (PER0) to 1 to start the supply of the input clock to the operational
<2> Use the A/D port configuration register (ADPC) to set the pins (AMPn−, AMPn+, AMPnO) to be used in single
<3> Use the port mode register x (PMx) to set the pins (AMPn−, AMPn+, AMPnO) to be used in single amplifier mode to
<4> Set (1) the OAENn bit of operational amplifier control register (OAC) and enable operation in single amplifier mode.
<5> Use software to wait until the operational amplifier stabilizes (turn-on time: 20
The operational amplifiers 0 to 2 have the following mode.
• Single AMP mode (operational amplifiers 0 to 2)
In single amplifier mode, the difference in potential of analog voltages input from two pins (AMPn− and AMPn+ pins) is
The amplified voltage can be used as an analog input of the A/D converter, because the AMPnO pin is alternatively
The procedure for starting operation in single amplifier mode is described below.
Caution To use as an input of the A/D converter a voltage that has been amplified in single amplifier mode,
