The status register indicates operating status of the flash memory and status such as whether an erase
operation or a program ended successfully or in error. It can be read by writing the read status register
command (70
Table 32.2 gives the definition of each status register bit. After clearing the reset, the status register
outputs “80

A
The write state machine (WSM) status indicates the operating status of the flash memory. When
power is turned on, “1” (ready) is set for it. The bit is set to “0” (busy) during an auto write or auto erase
operation, but it is set back to “1” when the operation ends.
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”.
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”.
If excessive data is written (phenomenon whereby the memory cell becomes depressed which results
in data not being read correctly), “1” is set for the program status after-program at the end of the page
write operation. In other words, when writing ends successfully, “80
“90
If “1” is written for any of the 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 command (50
