FIGURE 4. RECALL COMMAND SEQUENCE
RECALL COMMAND
The recall command will retrieve data from the selected
nonvolatile register and write it into the data register of the
associated DAC. This operation is initiated by taking
CS
LOW and clocking in a start bit followed by the recall
command and the address of the nonvolatile register to be
recalled. The eight bits of data are don’t care, so
CS
can
be taken high any time after the address bits are clocked
in. Refer to Figure 4 for an illustration of the sequence of
bus conditions for a Recall operation.
Power-On Recall
Whenever the S9418 is powered on, the V
OUT
values will
be returned to the analog equivalent of the data byte
stored in the nonvolatile register.
MUTE Operation
The MUTE input is active high. Whenever the input is low,
the V
OUT
will reflect the value in the data register. If MUTE
is driven high the V
OUT
outputs will be switched to V
REFL
.
Releasing the MUTE input returns the V
OUT
outputs to the
analog equivalent of the data register contents.
