Description
Reset the scratch pad register with current contents of the EEMEM register. Factory defaults midscale before any programming
Write Protect Pin. When active low,
WP
prevents any changes to the present register contents, except
PR
and cmd 1 and 8 will refresh the
RDAC register from EEMEM. Execute a NOP instruction before returning to
WP
high.
Serial Input Register clock pin. Shifts in one bit at a time on positive clock edges.
Serial Data Input Pin. Shifts in one bit at a time on positive clock CLK edges. MSB loaded first.
Ground pin, logic ground reference
Negative Supply. Connect to zero volts for single supply applications.
A terminal of RDAC2.
