Program Error

1*

* Program Interleave can work in Auto INT

Check the chip status before command issues.Mode.

2*

Previous Program Status Check

Interrupt register must not be written.

3*

DBS must be changed to indicate chip. Program has been issued prior to current program ongoing Final Program Status Check

NOTE :

1)DBS must be set before data input.

2)FSA must be 00 and BSC must be 000 within program operation

3)BSA must be 1000 and BSC must be 000.
