Clear Compare Status (89H)
The Clear Compare Status command (89H) works in con-
junction with the Compare Sector to SRAM command and
the Status Register. If any of the compared bits are not
equal, then the Compare Not Equal (CNE) bit in the Status
Register is set to a 1. The Clear Compare Status command
must be executed to reset the CNE bit to a 0.

Set Power Detection Bit (03H)
The Set Power Detection Bit command (03H) can be used
to detect if power has been removed from the device. The
command works in conjunction with the Power Detect (PD)
status bit. Upon power up the PD bit is cleared to 0. The PD
bit can be set to a 1 using the Set Power Detection Bit
command. Once set, if a power down condition occurs
(Vcc voltage < 2V) the PD bit will reset to 0. This function
is especially useful for applications using NexFlash Serial
Flash Modules or other removable media.

Reset Power Detection Bit (09H)
The Reset Power Detection Bit command (09H) can be used
to force the Power Detect Status bit in the status register to
a 0 state. (see Set Power Detection Bit command (03H).
