3. Write a 1 to the FCBEF bit in FSTAT to clear FCBEF and launch the command (including its
4. Wait until the FCCF bit in FSTAT is set. As soon as FCCF= 1, the operation has completed
address and data information).
A partial command sequence can be aborted manually by writing a 0 to FCBEF any time after the
write to the memory array and before writing the 1 that clears FCBEF and launches the complete
command. Aborting a command in this way sets the FACCERR access error flag which must be
cleared before starting a new command.
A strictly monitored procedure must be obeyed or the command will not be accepted. This
minimizes the possibility of any unintended changes to the memory contents. The command
complete flag (FCCF) indicates when a command is complete. The command sequence must be
completed by clearing FCBEF to launch the command.
