DACEN: DAC Enable bit
1 = Module is enabled
0 = Module is disabled
Unimplemented: Read as ‘0’
DACSIDL: DAC Peripheral Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
DACSLP: DAC Enable Peripheral During Sleep bit
1 = DAC continues to output the most recent value of DACxDAT during Sleep mode
0 = DAC is powered down in Sleep mode; DACx output pin is controlled by the TRISx and LATx bits
DACFM: DAC Data Format Select bit
1 = Data is left justified (data stored in DACxDAT<15:5>)
0 = Data is right justified (data stored in DACxDAT<9:0>)
Unimplemented: Read as ‘0’
DACTRIG: DAC Trigger Input Enable bit
1 = Analog output value updates when the selected (by DACTSEL<4:0>) event occurs
0 = Analog output value updates as soon as DACxDAT is written (DAC trigger is ignored)
Unimplemented: Recommended to write as ‘1’ for code compatibility across device families
DACTSEL<4:0>: DAC Trigger Source Select bits
11x = Unimplemented
101 = S/D A/D interrupt
100 = Pipeline A/D interrupt
011 = Timer1 interrupt
010 = Timer2 interrupt
001 = INT1
000 = Comparator 1 trigger
DACREF<1:0>: DAC Reference Source Select bits
11 = 2.4V Internal Band Gap (2 • BGBUF0)⁽¹⁾
10 = AVDD
01 = DVREF+
00 = Reference not connected (lowest power but no DAC functionality)
Note 1: User must also enable Band Gap Buffer 0 and set BUFCON0<1:0> to ‘00’ to obtain this voltage. See
Register 25-1 for details.
