Hardware Shutdown pin Status bit (Refer to
for further information)
This bit indicates if the Hardware shutdown pin (SHDN) is low. A hardware shutdown disconnects the
Terminal A and forces the wiper (Terminal W) to Terminal B (see
While the device is in Hard-
ware Shutdown (the SHDN pin is low) the serial interface is operational so the STATUS register may be
read.
