Bulk Erase (BE)
The Bulk Erase (BE) command sets all the bits within the entire memory array to logic 1s. A WREN command
is required prior to writing the PP command.
The host system must drive CS# low, and then write the BE command on SI. CS# must be driven low for the
entire duration of the BE sequence. The command sequence is shown in
on page
The host system must drive CS# high after the device has latched the 8th bit of the CE command, otherwise
the device does not execute the command. The BE operation begins as soon as CS# is driven high. The
device internally controls the timing of the operation, which requires a period of t
be read to check the value of the Write In Progress (WIP) bit while the BE operation is in progress. The WIP
bit is 1 during the BE 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 only executes a BE command if all Block Protect bits (BP2:BP0) are 0 (see
on page
28.
13). Otherwise, the device ignores the command.
