The CONFIG command (B[23:20] = 0101) updates
the function of the AUX input enabling its gate or clear
(default) operation mode. See
AUX Config settings are written by B[5:3]:
GATE (011):
CLEAR (110):
NONE (111):

AUX functions as a GATE. DAC code is
gated to DEFAULT value input when pin
is low.
AUX functions as a CLR input (default).
CODE and DAC content is cleared to
DEFAULT value if pin is low.
AUX functions are disabled.
AUX function is not altered.

DEFAULT (0110): The DEFAULT command selects the
default value for the DAC. These default values are used
for all future clear and gate operations. The new default
setting is determined by bits DF[2:0]. See
Available default values are:
POR (000):
ZERO (001):
MID (010):
FULL (011):
RETURN (100): DAC defaults to value specified by the
OTHER:
Note: The selected default values do not apply to resets
initiated by SW_RESET commands or supply cycling,
both of which return the DACs to the power-on reset state
(zero scale).
