8.5 HOLD OPERATION

HOLD# is used in conjunction with CE# to select the device. When the device is selected and a serial sequence is

underway, HOLD# can be used to pause the serial communication with the master device without resetting the

serial sequence. To pause, HOLD# is brought low while the SCK signal is low. To resume serial communication,

HOLD# is brought high while the SCK signal is low (SCK may still toggle during HOLD). Inputs to SI will be ignored

while SO is in the high impedance state, during HOLD.

Note: HOLD is not supported in DTR mode or with QE=1 or when RESET# is selected for the HOLD# or RESET# pin.

Timing graph can be referenced in AC Parameters Figure 9.4.
