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:
During embedded algorithm error status the Status Register will show the following:
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 by
writing:
Commands that are accepted during embedded algorithm error status are:

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 = 1 to indicate embedded sector erase in progress
DQ2 does not toggle as no erase is in progress
DQ1 = 1: Write buffer abort error
DQ0 is RFU and should be treated as don’t care (masked)

Status Register Clear command
–
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)
Write Buffer Abort Reset command
Status Register Read
Write Buffer Abort Reset command
Status Register Clear command
Clears the status register and returns to normal operation
Reads the status register and returns to WBA busy state
