Address 20:16  
ADD(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.

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 BSY bits  
are reset as well; for this reason, it is definitively meaningful reading FER register content  
only when LOCK bit and all BSY bits are cleared.

Table 17. Flash error register  
Bit  
Function  
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.  
ERR  
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.  
ERER  
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.  
PGER  
10ER  
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.
