Write-Status-Register (WRSR)

The Write Status Register instruction writes new values to the

BP2,  BP1,  BP0,  TB  and  BPL  bits  of  the  status  register.  CE
must be driven low before the command sequence of the WRSR
instruction  is  entered  and  driven  high  before  the  WRSR
instruction  is  executed.  See  Figure  14  for  WREN  and  WRSR
instruction sequences.

Executing  the  Write  Status  Register  instruction  will  be  ignored

when WP is low and BPL bit is set to “1”. When the WP is
low, the BPL bit can only be set from “0” to “1” to lock down the
status register, but cannot be reset from “1” to “0”.

When WP is high, the lock-down function of the BPL bit is
disabled and the BPL, TB, BP0, BP1,and BP2 bits in the status

register can all be changed. As long as BPL bit is set to 0 or WP
pin is driven high (V

IH

) prior to the low-to-high transition of the

CE pin at the end of the WRSR instruction, the bits in the status

register can all be altered by the WRSR instruction. In this case,
a single WRSR instruction can set the BPL bit to “1” to lock down
the status register as well as altering the TB, BP0; BP1 and BP2
bits at the same time. See Table 4 for a summary description of

WP and BPL functions.
