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 * (AV
DD/2)/1024) volts depending on Range bit
·····
0000000000 = 0.0 volts
