Write State Machine (WSM) Status (SR7)
The write state machine (WSM) status indicates the operating status of the flash memory. When power is turned on,
"1" (ready) is set. The bit is set to "0" (busy) during an auto-write or auto-erase operation, but returns to "1" when the
operation ends.
Erase Status (SR5)
The erase status reports the operating status of the auto-erase operation. If an erase error occurs, it is set to "1".
When the erase status is cleared, it is set to "0".
Program Status (SR4)
The program status reports the operating status of the auto-write operation. If a write error occurs, it is set to "1".
When the program status is cleared, it is set to "0".
Block Status After Program (SR3)
If data is overwritten (this occurs when a memory cell becomes overcharged and data is incorrectly read), a "1" is set
for the block status after program at the end of the page write operation.
In other words:
• When writing ends successfully "80
• When writing fails, "90
• When excessive data is written, "88
If "1" is written to any SR5, SR4 or SR3 bits, the page program, block erase, erase all unlocked blocks and lock bit
program commands are not accepted. Before executing these commands, execute the clear status register com-

Status Register 1 (SRD1)
Status register 1 indicates the status of serial communications, ID check results, and check sum comparisons. It
can be read after the SRD by writing the read status register command (70
