Page Program (PP) Command Sequence
9.9
Sector Erase (SE)
The Sector Erase (SE) command sets all bits at all addresses within a specified sector to a logic 1. A WREN
command is required prior to writing the PP command.
The host system must drive CS# low, and then write the SE command plus three address bytes on SI. Any
address within the sector (see
Table 7.1 on page 11
) is a valid address for the SE command. CS# must be
driven low for the entire duration of the SE sequence. The command sequence is shown in
Figure 9.9
and
Table 9.4
.
The host system must drive CS# high after the device has latched the 8th bit of the SE command, otherwise
the device does not execute the command. The SE operation begins as soon as CS# is driven high. The
device internally controls the timing of the operation, which requires a period of t
SE
. The Status Register may
be read to check the value of the Write In Progress (WIP) bit while the SE operation is in progress. The WIP
bit is 1 during the SE operation, and is 0 when the operation is completed. The device internally resets the
Write Enable Latch to 0 before the operation completes (the exact timing is not specified).
The device does not execute an SE command that specifies a sector that is protected by the Block Protect
bits (BP2:BP0) (see
Table 7.1 on page 11
).
