Write buffer abort

If an error occurs during a Write to Buffer command the device (EAC) remains busy. The RY/BY# output remains

LOW, data polling status continues to be overlaid on all address locations, and the status register shows ready

with valid status bits. The device remains busy until the error status is detected by the host system status

monitoring and the error status is cleared.

During write to buffer abort (WBA) error status the Data Polling status will show the following:

• DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer

• DQ6 continues to toggle, independent of the address used to read status

• DQ5 = 0; to indicate no failure of the programming operation. WBA is an error in the values input by the Write

to Buffer command before the programming operation can begin

• DQ4 is RFU and should be treated as don’t care (masked)

• DQ3 is don’t care after program operation as no erase is in progress. If the Write Buffer Program operation was

started after an erase operation had been suspended then DQ3 = 1. If there was no erase operation in progress

then DQ3 is a don’t care and should be masked.

• DQ2 does not toggle after program operation as no erase is in progress. If the Write Buffer Program operation

was started after an erase operation had been suspended then DQ2 will toggle in the sector where the erase

operation was suspended and not in any other sector. If there was no erase operation in progress then DQ2 is

a don’t care and should be masked.

• DQ1 = 1: Write buffer abort error

• DQ0 is RFU and should be treated as don’t care (masked)

During embedded algorithm error status the Status Register will show the following:

• SR[7] = 1; Valid status displayed

• SR[6] = X; May or may not be erase suspended during the WBA error status

• SR[5] = 0; Erase successful

• SR[4] = 1; Programming related error

• SR[3] = 1; Write buffer abort

• SR[2] = 0; No Program in suspension

• SR[1] = 0; Sector not locked during operation

• SR[0] = X; RFU, treat as don’t care (masked)

When the WBA error status is detected, it is necessary to clear the error status in order to return to normal

operation, with RY/BY# HIGH, ready for a new read or command write. The error status can be cleared and device
