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
0
= DAC is disabled
1
= DAC is enabled
bit 6
DACLPS: DAC Low-Power Voltage State Select bit
0
=VDAC = DAC Negative reference source selected
1
=VDAC = DAC Positive 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

-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 = ((VSOURCE+) - (VSOURCE-))*(DACR<4:0>/(2^5)) + VSOURCE-
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.
