Reset (RS) Pin Operation
The Reset pin (RS) will automatically set all potentiom-
eter data latches to mid-scale (Code 80h) when pulled
low (provided that the pin is held low at least 150 ns
and CS is high). The reset will execute regardless of
the position of the SCK, SHDN and SI pins. It is possi-
ble to toggle RS low and back high while SHDN is low.
In this case, the potentiometer registers will reset to
mid-scale, but the potentiometer will remain in
shutdown mode until the SHDN pin is raised.
5.6
Shutdown (SHDN) Pin Operation
When held low, the shutdown pin causes the applica-
tion circuit to go into a power-saving mode by open-cir-
cuiting the A terminal and shorting the B and W
terminals for all potentiometers. Data register contents
are not affected by entering shutdown mode (i.e., when
the SHDN pin is raised, the data register contents are
the same as before the shutdown mode was entered).
While in shutdown mode, it is still possible to clock in
new values for the data registers, as well as toggling
the RS pin to cause all data registers to go to mid-scale.
The new values will take affect when the SHDN pin is
raised.
If the device is powered-up with the SHDN pin held low,
it will power-up in the shutdown mode with the data reg-
isters set to mid-scale.
5.7
Power-up Considerations
When the device is powered on, the data registers will
be set to mid-scale (80h). A power-on reset circuit is
utilized to ensure that the device powers up in this
known state.
Note:
Bringing the RS pin low while the CS pin is
low constitutes an invalid operating state
and will result in indeterminate results
when RS and/or CS are brought high.
Note:
Bringing the SHDN pin low while the CS
pin is low constitutes an invalid operating
state and will result in indeterminate
results when SHDN and/or CS are brought
high.
