Operating features
Hold condition
The Hold (HOLD) signal is used to pause any serial communications with the device without
resetting the clocking sequence.
During the Hold condition, the Serial Data Output (Q) is high impedance, and Serial Data
Input (D) and Serial Clock (C) are Don’t Care.
To enter the Hold condition, the device must be selected, with Chip Select (S) low.
Normally, the device is kept selected, for the whole duration of the Hold condition.
Deselecting the device while it is in the Hold condition has the effect of resetting the state of
the device, and this mechanism can be used if it is required to reset any processes that had
been in progress.
The Hold condition starts when the Hold (HOLD) signal is driven low at the same time as
Serial Clock (C) already being low (as shown in
The Hold condition ends when the Hold (HOLD) signal is driven high at the same time as
Serial Clock (C) already being low.
