Notes

7. Bits 15 thru 8, and 0 are reserved for future use and may display as ‘0’ or ‘1’. These bits should be ignored

(masked) when checking status.

8. Bit 7 is 1 when there is no Embedded Algorithm in progress in the device.

9. Bits 6 thru 1 are valid only if Bit 7 is ‘1’.

10.All bits are put in their reset status by cold reset or warm reset.

11.Bits 5, 4, 3, and 1 are cleared to ‘0’ by the Clear Status Register command or Reset command.

12.Upon issuing the Erase Suspend Command, the user must continue to read status until DRB becomes ‘1’.

13.ESSB is cleared to ‘0’ by the Erase Resume command.

14.ESB reflects success or failure of the most recent erase operation.

15.PSB reflects success or failure of the most recent program operation.

16.During erase suspend, programming to the suspended sector, will cause program failure and set the Program

status bit to ‘1’.

17.Upon issuing the Program Suspend command, the user must continue to read status until DRB becomes ‘1’.

18.PSSB is cleared to ‘0’ by the Program Resume command.

19.SLSB indicates that a program or erase operation failed because the sector was locked.

20.SLSB reflects the status of the most recent program or erase operation.
