Embedded Operation Error
If an error occurs during an embedded operation (program, erase, blank check, or password unlock) 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 embedded algorithm error status the Data Polling status will show the following:
During embedded algorithm error status the Status Register will show the following:
When the embedded algorithm 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:

DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer or last word of the
password in the case of the password unlock command. DQ7 = 0 for an erase or blank check failure
DQ6 continues to toggle
DQ5 = 1; Failure of the embedded operation
DQ4 is RFU and should be treated as don’t care (masked)
DQ3 = 1 to indicate embedded sector erase in progress
DQ2 continues to toggle, independent of the address used to read status
DQ1 = 1; Write buffer abort error
DQ0 is RFU and should be treated as don’t care (masked)
SR[7] = 1; Valid status displayed
SR[6] = X; May or may not be erase suspended during the EA error
SR[5] = 1 on erase or blank check error; else = 0
SR[4] = 1 on program or password unlock error; else = 0
SR[3] = 1; Write buffer abort
SR[2] = 1; Program suspended
SR[1] = 1; Protected sector
SR[0] = X; RFU, treat as don’t care (masked)
