Table 19-1.
In order to perform one of these commands, the Flash Command Register (MC_FCR) has to be
written with the correct command using the field FCMD. As soon as the MC_FCR register is writ-
ten, the FRDY flag and the field FVALUE in the MC_FRR register are automatically
cleared. Once the current command is achieved, then the FRDY flag is automatically set. If an
interrupt has been enabled by setting the bit FRDY in MC_FMR, the interrupt line of the Memory
Controller is activated.
All the commands are protected by the same keyword, which has to be written in the 8 highest
bits of the MC_FCR register.
Writing MC_FCR with data that does not contain the correct key and/or with an invalid command
has no effect on the whole memory plane, but the FCMDE flag is set in the MC_FSR register.
This flag is automatically cleared by a read access to the MC_FSR register.
When the current command writes or erases a page in a locked region, the command has no
effect on the whole memory plane, but the FLOCKE flag is set in the MC_FSR register. This flag
is automatically cleared by a read access to the MC_FSR register.
