23A1024/23LC1024

selected and a serial sequence is underway, the HOLD

pin may be pulled low to pause further serial

communication without resetting the serial sequence.

The HOLD pin should be brought low while SCK is low,

otherwise the HOLD function will not be invoked until

the

SCK

high-to-low

transition.

The

23A1024/23LC1024 must remain selected during this

sequence. The SI and SCK levels are “don’t cares”

during the time the device is paused and any

transitions on these pins will be ignored. To resume

serial communication, HOLD should be brought high

while

the

SCK

low,

otherwise

serial

communication will not be resumed until the next SCK

high-to-low transition.

The SO line will tri-state immediately upon a high-to low

transition of the HOLD pin, and will begin outputting

again immediately upon a subsequent low-to-high

transition of the HOLD pin, independent of the state of

SCK.

Hold functionality is not available when operating in

SQI bus mode.
