4.6 Write Status Register ( WRSR )
Instruction
The WRSR instruction allows the user to select one of
four levels of protection for the array by writing to the
appropriate bits in the STATUS register. The array is
divided up into four segments. The user has the ability
to write-protect none, one, two, or all four of the seg-
ments of the array. The partitioning is controlled as
illustrated in Table 4-3.
After transmitting the STATUS register data, the master
must transmit a NoMAK during the Acknowledge
sequence in order to initiate the internal write cycle.
Note: The WRSR instruction must be termi-
nated with a NoMAK following the data
byte. If a NoMAK is not received at this
point, the command will be considered
invalid, and the device will go into Idle
mode without responding with a SAK or
executing the command.
