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 DACLPS: DAC Low-Power Voltage State Select bit
1 = DAC Positive reference source selected
0 = DAC Negative reference source selected
bit 5 DACOE: DAC Voltage Output Enable bit
1 = DAC voltage level is also an output on the DACOUT pin
0 = DAC voltage level is disconnected from the DACOUT pin
bit 4 Unimplemented: Read as ‘0’
bit 3-2 DACPSS<1:0>: DAC Positive Source Select bits
00 = VDD
01 =VREF+ pin
10 = FVR Buffer2 output
