Protection Error
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:
Commands that are accepted during embedded algorithm error status are:
If an embedded algorithm attempts to change data within a protected area (program, or erase of a protected
sector or OTP area) the device (EAC) goes busy for a period of 20 to 100 µs then returns to normal operation.
During the busy period the RY/BY# output remains Low, data polling status continues to be overlaid on all
address locations, and the status register shows not ready with invalid status bits (SR[7] = 0).
During the protection error status busy period the data polling status will show the following:
Commands that are accepted during the protection error status busy period are:
When the busy period ends the device returns to normal operation, the data polling status is no longer
overlaid, RY/BY# is High, and the status register shows ready with valid status bits. The device is ready for
flash array read or write of a new command.
D a t a
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)
DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer. DQ7 = 0 for an erase
failure
DQ6 continues to toggle, independent of the address used to read status
DQ5 = 0; to indicate no failure of the embedded operation during the busy period
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)
