Resets the scratchpad register with current contents of the EEMEM register. Factory defaults to midscale before
any programming.
Write Protect. When active low, WP prevents any changes to the present register contents, except that RESET
and Commands 1 and 8 still refresh the RDAC register from EEMEM.
Serial Input Register Clock. Shifts in one bit at a time on the positive clock edges.
Serial Data Input. Shifts in one bit at a time on the positive clock edges. The MSB is loaded first.
Ground. Logic ground reference.
Negative Supply. Connect to 0 V for single-supply applications.
