For the reserved values, all input switches are disabled to avoid leakage or other undesir-
able operation. ADC samples taken with reserved bit settings are undefined.
SINGLE-ENDED Mode:
0000 = ANA0 (transimpedance amp output when enabled)ï
0001 = ANA1 (transimpedance amp inverting input)ï
0010 = ANA2 (transimpedance amp noninverting input)ï
0011 = ANA3ï
0100 = ANA4ï
0101 = ANA5ï
0110 = ANA6ï
0111 = ANA7ï
1000 = Reservedï
1001 = Reservedï
1010 = Reservedï
1011 = Reservedï
1100 = Hold transimpedance input nodes (ANA1 and ANA2) to ground.ï
1101 = Reservedï
1110 = Temperature Sensor.ï
1111 = Reserved.
DIFFERENTIAL Mode (noninverting input and inverting input respectively):
0000 = ANA0 and ANA1ï
0001 = ANA2 and ANA3ï
0010 = ANA4 and ANA5ï
0011 = ANA1 and ANA0ï
0100 = ANA3 and ANA2ï
0101 = ANA5 and ANA4ï
0110 = ANA6 and ANA5ï
0111 = ANA0 and ANA2ï
1000 = ANA0 and ANA3ï
1001 = ANA0 and ANA4ï
1010 = ANA0 and ANA5ï
1011 = Reservedï
1100 = Reservedï
1101 = Reservedï
1110 = Reservedï
1111 = Manual Offset Calibration Mode
ADC Control/Status Register 1
The ADC Control/Status Register 1 (ADCCTL1) configures the input buffer stage,
enables the threshold interrupts and contains the status of both threshold triggers. It is also
used to select the voltage reference configuration.
