Hold Function  
The Hold (HOLD#) signal is used to pause any serial communications with the device without resetting  
the clocking sequence. However, taking this signal Low does not terminate any Write Status Register,  
Program or Erase cycle that is currently in progress.  
To enter the Hold condition, the device must be selected, with Chip Select (CS#) Low. The Hold  
condition starts on the falling edge of the Hold (HOLD#) signal, provided that this coincides with Serial  
Clock (CLK) being Low (as shown in Figure 4.).  
The Hold condition ends on the rising edge of the Hold (HOLD#) signal, provided that this coincides  
with Serial Clock (CLK) being Low.  
If the falling edge does not coincide with Serial Clock (CLK) being Low, the Hold condition starts after  
Serial Clock (CLK) next goes Low. Similarly, if the rising edge does not coincide with Serial Clock (CLK)  
being Low, the Hold condition ends after Serial Clock (CLK) next goes Low. (This is shown in Figure 4.).  
During the Hold condition, the Serial Data Output (DO) is high impedance, and Serial Data Input (DI)  
and Serial Clock (CLK) are Don’t Care.  
Normally, the device is kept selected, with Chip Select (CS#) driven Low, for the whole duration of the  
Hold condition. This is to ensure that the state of the internal logic remains unchanged from the mo-  
ment of entering the Hold condition.  
If Chip Select (CS#) goes High while the device is in the Hold condition, this has the effect of resetting  
the internal logic of the device. To restart communication with the device, it is necessary to drive Hold  
(HOLD#) High, and then to drive Chip Select (CS#) Low. This prevents the device from going back to  
the Hold condition.
