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 1.22.3 gives the definition of each status register bit. After clearing the reset, the status register
outputs “80
Sequencer status (SR7)
Erase Status (SR5)
Program Status (SR4)
After power-on, the sequencer status is set to 1(ready).
The sequencer status indicates the operating status of the device. This status bit is set to “0” (busy)
during write or erase operation and is set to 1 upon completion of these operations.
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”.
