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
