Gate Configuration:
The DAC GATE setting is written by GTB (B5); GATE
operation is as follows:
GTB = 0: Enables software gating function (default), DAC
outputs are gated to their DEFAULT settings as long as
the device remains in GATE mode (set by SW_GATE_
SET and removed by SW_GATE_CLR).
GTB = 1: Disable software gating function, DAC outputs
are not impacted by GATE mode.
Load Configuration:
The LDAC_ENB setting is written by LDB (B4);
LDAC_ENB operation is as follows:
LDB = 0: DAC latch is operational, enabling LDAC and
LOAD functions (default).

LDB = 1: DAC latch is transparent, the CODE register
content controls the DAC output directly.
Clear Configuration:
CLEAR_ENB setting is written by CLB (B3); CLEAR_ENB
operation is as follows:
CLB = 0: Clear input and command functions impact the
DAC (default), clearing CODE and DAC registers to their
DEFAULT value.
CLB = 1: Clear input and command functions have no
effect on the DAC.
