R = Readable bit
u = bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets

bit 0
DACEN: DAC Enable bit
0 = DAC is disabled
1 = DAC is enabled
DACLPS: DAC Low-Power Voltage State Select bit
0 = VDAC = DAC Negative reference source selected
1 = VDAC = DAC Positive reference source selected
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
Unimplemented: Read as ‘0’
DACPSS<1:0>: DAC Positive Source Select bits
00 = VDD
01 = VREF+
10 = FVR1 output
11 = Reserved, do not use
Unimplemented: Read as ‘0’
DACNSS: DAC Negative Source Select bits
0 = VSS
1 = VREF-

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.
