R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets

DAC1EN: DAC1 Enable bit
1 = DAC is enabled
0 = DAC is disabled
Unimplemented: Read as ‘0’
DAC1OE1: DAC1 Voltage Output 1 Enable bit
1 = DAC voltage level is also an output on the DAC1OUT1 pin
0 = DAC voltage level is disconnected from the DAC1OUT1 pin
DAC1OE2: DAC1 Voltage Output 1 Enable bit
1 = DAC voltage level is also an output on the DAC1OUT2 pin
0 = DAC voltage level is disconnected from the DAC1OUT2 pin
DAC1PSS<1:0>: DAC1 Positive Source Select bits
11 = Reserved, do not use
10 = FVR output
01 = VREF+ pin
00 = VDD
Unimplemented: Read as ‘0’
DAC1NSS: DAC1 Negative Source Select bits
1 = VREF- pin
0 = VSS
