Flash error register
Flash Error register, as well as all the other Flash registers, can be properly read only once
LOCK bit of register FCR0L is low. Nevertheless, its content is updated when also BSYx bits
are reset as well; for this reason, it is definitively meaningful reading FER register content
only when LOCK bit and BSYx bits are cleared.

Address 20:16
These bits must be written with the Address of the Flash location to program in the following
operations: Word Program and Double Word Program.
Write error
This bit is automatically set when an error occurs during a Flash write operation or when a bad
write operation setup is done. Once the error has been discovered and understood, ERR bit must
be software reset.
Erase error
This bit is automatically set when an Erase error occurs during a Flash write operation. This error
is due to a real failure of a Flash cell, that can no more be erased. This kind of error is fatal and the
sector where it occurred must be discarded. This bit has to be software reset.
Program error
This bit is automatically set when a Program error occurs during a Flash write operation. This error
is due to a real failure of a Flash cell, that can no more be programmed. The word where this error
occurred must be discarded. This bit has to be software reset.
1 over 0 error
This bit is automatically set when trying to program at 1 bits previously set at 0 (this does not
happen when programming the Protection bits). This error is not due to a failure of the Flash cell,
but only flags that the desired data has not been written. This bit has to be software reset.
Sequence error
This bit is automatically set when the control registers (FCR1H/L-FCR0H/L, FARH/L, FDR1H/L-
FDR0H/L) are not correctly filled to execute a valid Write Operation. In this case no Write
Operation is executed. This bit has to be software reset.
