is the decimal equivalent of the code loaded to the DAC.

is the reference voltage applied at the REFAB/REFCD
pins.
ASYNCHRONOUS CLEAR (CLR)
CLR is a negative edge triggered clear that allows the outputs to
be cleared to either 0 V (twos complement coding) or negative
full scale (offset binary coding). It is necessary to maintain CLR
low for a minimum amount of time (see Figure 3) for the
operation to complete. When the CLR signal is returned high,
the output remains at the cleared value until a new value is
programmed. If at power-on CLR is at 0 V, then all DAC
outputs are updated with the clear value. A clear can also be
initiated through software by writing the command 0x04XXXX
to the AD5764R.
