SECTOR ERASE
The
SECTOR ERASE
instruction will erase all bits
(FFh) inside the given sector. A Write Enable (
WREN
)
instruction must be given prior to attempting a
SECTOR
ERASE
. This is done by setting CS low and then clock-
ing out the proper instruction into the 25XX512. After
all eight bits of the instruction are transmitted, the CS
must be brought high to set the write enable latch.
The
SECTOR ERASE
instruction is entered by driving
CS low, followed by the instruction code (Figure 2-9)
and two address bytes. Any address inside the sector
to be erased is a valid address.
CS must then be driven high after the last bit of the
address or the
SECTOR ERASE
will not execute. Once
the CS is driven high the self-timed
SECTOR ERASE
cycle is started. The WIP bit in the STATUS register
can be read to determine when the
SECTOR ERASE
cycle is complete.
If a
SECTOR ERASE
instruction is given to an address
that has been protected by the Block Protect bits (BP0,
BP1) then the sequence will be aborted and no erase
will occur.
See Table 2-3 for Sector Addressing.
