• FRDY: Flash Ready Status
0: The Enhanced Embedded Flash Controller (EEFC) is busy.
1: The Enhanced Embedded Flash Controller (EEFC) is ready to start a new command.
When it is set, this flags triggers an interrupt if the FRDY flag is set in the EEFC_FMR register.
This flag is automatically cleared when the Enhanced Embedded Flash Controller (EEFC) is busy.
• FCMDE: Flash Command Error Status
0: No invalid commands and no bad keywords were written in the Flash Mode Register EEFC_FMR.
1: An invalid command and/or a bad keyword was/were written in the Flash Mode Register EEFC_FMR.
This flag is automatically cleared when EEFC_FSR is read or EEFC_FCR is written.
• FLOCKE: Flash Lock Error Status
0: No programming/erase of at least one locked region has happened since the last read of EEFC_FSR.
1: Programming/erase of at least one locked region has happened since the last read of EEFC_FSR.
This flag is automatically cleared when EEFC_FSR is read or EEFC_FCR is written.
