bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7
DACEN: DAC Enable bit
1 = DAC is enabled
0 = DAC is disabled
bit 6
Unimplemented: Read as ‘0’
bit 5
DACOE1: DAC Voltage Output 1 Enable bit
1 = DAC voltage level is also an output on the DACOUT1 pin
0 = DAC voltage level is disconnected from the DACOUT1 pin
bit 4
DACOE2: DAC Voltage Output 2 Enable bit
1 = DAC voltage level is also an output on the DACOUT2 pin
0 = DAC voltage level is disconnected from the DACOUT2 pin
bit 3-2
DACPSS<1:0>: DAC Positive Source Select bits
11 = Reserved, do not use
10 = FVR Buffer2 output
01 =VREF+ pin
00 =VDD
bit 1 Unimplemented: Read as ‘0’
bit 0
DACNSS: DAC Negative Source Select bits
1 =VREF- pin
0 =VSS
