WRITE AND UPDATE COMMANDS
Write to Input Register n (Dependent on
LDAC
)
Command 0001 allows the user to write to each DAC’s
dedicated input register individually. When
LDAC
is low,
the input register is transparent (if not controlled by the
LDAC
mask register).
Update DAC Register n with Contents of Input Register n
Command 0010 loads the DAC registers/outputs with the
contents of the input registers selected and updates the DAC
outputs directly.
Write to and Update DAC Channel n (Independent of
LDAC
)
Command 0011 allows the user to write to the DAC registers
and update the DAC outputs directly.
