The Flash Status Register FSR reflects the overall and also sector specific status of the Flash
module. Therefore the register address of the FSR is the sector address SLOC (as defined above)
where bit SE is sector specific and all other bits are identical within each sector.
FSR (
Sector Address)
Reset Value: 0000H
Note: The status register is a read-only register. Only the four error flags in the FSR are affected
with the “clear status” command, indicated by “r(w)”.
Bit
Function
BUSY
Flash Busy (Summarizes the single busy bits)
0: Ready. Flash command execution is completed, module is in std. read mode.
1: Busy. Embedded algorithms for command execution are in progress.
PROG
Programming State
0: There is no programming operation in progress.
1: Flash busy with programming operation (store burst in operation).
ERASE
Erase State
0: There is no erase operation in progress.
1: Flash busy with erase operation.
BRST
Burst Mode
0: Flash not in burst mode.
1: Flash in burst mode, i.e. assembly register being filled.
Note: Burst and read mode may occur concurrently.
OPER
Operation Error (Cleared via “Clear status” command)
0: Flash operation successfully terminated or currently running.
1: Flash array operation not successfully terminated, error in flash operation.
VPER
Voltage Error (Cleared via “Clear status” command)
0: No problem of programming voltage during Flash array operation.
1: Flash array operation not successful because of a prog. voltage problem.
SQER
Command Sequence Error (Cleared via “Clear status” command)
0: No command sequence error detected.
1: State machine operation aborted because of an illegal command sequence.
BUER
Burst Error (Cleared via “Clear status” command)
0: Burst operation successfully terminated or currently running.
1: Overflow or underload condition in burst mode detected.
SE
Sector Erased (Sector specific status bit)
0: Sector has not been erased since the last reset.
1: Sector has been successfully erased.
