DAC12
CALON
Bit 9
DAC12 calibration on. This bit initiates the DAC12 offset calibration sequence
and is automatically reset when the calibration completes.
0
Calibration is not active
1
Initiate calibration/calibration in progress
DAC12IR
Bit 8
DAC12 input range. This bit sets the reference input and voltage output range.
0
DAC12 full-scale output = 3x reference voltage
1
DAC12 full-scale output = 1x reference voltage
DAC12
AMPx
Bits
7-5
DAC12 amplifier setting. These bits select settling time vs. current
consumption for the DAC12 input and output amplifiers.

ENC
Bit 1
DAC12 enable conversion. This bit enables the DAC12 module when
DAC12LSELx > 0. when DAC12LSELx = 0, DAC12ENC is ignored.

1
DAC12 enabled
DAC12
GRP
Bit 0
DAC12 group. Groups DAC12_x with the next higher DAC12_x. Not used for
DAC12_1 on MSP430FG43x devices or on MSP430x42x0 devices.
0
Not grouped
1
