Status Register
The status register shows the operating status of the flash
memory and whether erase operations and programs ended
successfully or in error. It can be read in the following ways:
(1) By reading an arbitrary address from the User ROM area
after writing the read status register command (7016)
(2) By reading an arbitrary address from the User ROM area in
the period from when the program starts or erase operation
starts to when the read array command (FF16) is input.
Also, the status register can be cleared by writing the clear status
register command (5016).
After reset, the status register is set to “8016”.
Table 18 shows the status register. Each bit in this register is
explained below.
Sequencer status (SR7)
The sequencer status indicates the operating status of the flash
memory. This bit is set to “0” (busy) during write or erase
operation and is set to “1” when these operations ends.
After power-on, the sequencer status is set to “1” (ready).
Erase status (SR5)
The erase status indicates the operating status of erase operation.
If an erase error occurs, it is set to “1”. When the erase status is
cleared, it is reset to “0”.
Program status (SR4)
The program status indicates the operating status of write
operation.
When a write error occurs, it is set to “1”.
The program status is reset to “0” when it is cleared.
If “1” is written for any of the SR5 and SR4 bits, the read array,
program, and block erase commands are not accepted. Before
executing these commands, execute the clear status register
command (5016) and clear the status register.
Also, if any commands are not correct, both SR5 and SR4 are set
to “1”.
