Functional Description and Application Information
The burst program procedure can be used to program the entire Flash memory, even while crossing row boundaries within the
Flash array. If data to be burst programmed falls within a protected area of the Flash array, the PVIOL flag in the FSTAT register
will set and the burst program command will not launch. Once the burst program command has successfully launched, the CCIF
flag in the FSTAT register will set after the burst program operation has completed, unless a new burst program command write
sequence has been buffered. By executing a new burst program command write sequence on sequential addresses after the
CBEIF flag in the FSTAT register has been set, greater than 50% faster programming time for the entire Flash array can be
effectively achieved, when compared to using the basic program command.

Write the program burst command, 0x25, to the FCMD register.
Clear the CBEIF flag in the FSTAT register by writing a 1 to CBEIF to launch the program burst command.
After the CBEIF flag in the FSTAT register returns to a 1 (interrupt generated, if enabled), repeat steps
address written is ignored but is incremented internally.
