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

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 7-5
Unimplemented:
Read as ‘0’
bit 4-0
DACR<4:0>:
DAC Voltage Output Select bits
VOUT = ((VSRC+) - (VSRC-))*(DACR<4:0>/(25)) + VSRC-
Note 1:
The output select bits are always right justified to ensure that any number of bits can be used without
affecting the register layout.
