DACEN: DAC Enable bit
1 = DAC is enabled
0 = DAC is disabled
Unimplemented: Read as â0â
DACOE1: DAC Voltage Output Enable bit
1 = DAC voltage level is also an output on the DACOUT1 pin
0 = DAC voltage level is disconnected from the DACOUT1 pin
DACOE2: DAC Voltage Output Enable bit
1 = DAC voltage level is also an output on the DACOUT2 pin
0 = DAC voltage level is disconnected from the DACOUT2 pin
Unimplemented: Read as â0â
DACPSS: DAC Positive Source Select bit
1 = VREF+ pin
0 = VDD
Unimplemented: Read as â0â
