RB
I/O
An erase operation consists of the following three steps (refer to
1.
2.
3.
The operation is initiated on the rising edge of Write Enable, W, after the Confirm command
is issued. The P/E/R controller handles block erase and implements the verify process.
During the block erase operation, only the Read Status Register and Reset commands are
accepted; all other commands are ignored.
Once the program operation has completed, the P/E/R controller bit SR6 is set to ‘1’ and the
Ready/Busy signal goes High. If the operation completed successfully, the write status bit
SR0 is ‘0’, otherwise it is set to ‘1’.
Block Erase
Setup Code
One bus cycle is required to set up the Block Erase command. Only addresses A18-
A28 are used; all other address inputs are ignored
Three bus cycles are then required to load the address of the block to be erased. Refer
to
One bus cycle is required to issue the Block Erase Confirm command to start the P/E/R
controller.
