Status Register
M50FLW080A, M50FLW080B
5.3
Erase status (bit SR5)
This bit indicates if a problem has occurred during the erasing of a Sector or Block. The
Erase Status bit should be read once the Program/Erase Controller Status bit is ‘1’
(Program/Erase Controller inactive).
When the Erase Status bit is ‘0’, the memory has successfully verified that the Sector/Block
has been erased correctly. When the Erase Status bit is ‘1’, the Program/Erase Controller
has applied the maximum number of pulses to the Sector/Block and still failed to verify that
the Sector/Block has been erased correctly.
Once the Erase Status bit is set to ‘1’, it can only be reset to ‘0’ by a Clear Status Register
command, or by a hardware reset. If it is set to ‘1’, it should be reset before a new Program
or Erase command is issued, otherwise the new command will appear to have failed, too.
5.4
Program status (bit SR4)
This bit indicates if a problem has occurred during the programming of a byte. The Program
Status bit should be read once the Program/Erase Controller Status bit is ‘1’
(Program/Erase Controller inactive).
When the Program Status bit is ‘0’, the memory has successfully verified that the byte has
been programmed correctly. When the Program Status bit is ‘1’, the Program/Erase
Controller has applied the maximum number of pulses to the byte and still failed to verify
that the byte has been programmed correctly.
Once the Program Status bit is set to ‘1’, it can only be reset to ‘0’ by a Clear Status Register
command, or by a hardware reset. If it is set to ‘1’, it should be reset before a new Program
or Erase command is issued, otherwise the new command will appear to have failed, too.
5.5
VPP status (bit SR3)
This bit indicates whether an invalid voltage was detected on the VPP pin at the beginning of
a Program or Erase operation. The VPP pin is only sampled at the beginning of the
operation. Indeterminate results can occur if VPP becomes invalid during a Program or
Erase operation.
Once the VPP Status bit set to ‘1’, it can only be reset to ‘0’ by a Clear Status Register
command, or by a hardware reset. If it is set to ‘1’, it should be reset before a new Program
or Erase command is issued, otherwise the new command will appear to have failed, too.
