Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-10
Reserved: Read as ‘0’
These bits are reserved for possible future expansion of the DAC from 10 bits to more bits.
bit 9-0
CMREF<9:0>: Comparator Reference Voltage Select bits
1111111111
= (CMREF * INTREF/1024) or (CMREF * (AVDD/2)/1024) volts depending on Range bit
0000000000
= 0.0 volts
