Offset: 0x4
The FCMD can not be written if the flash is in the process of performing a flash command.
Doing so will cause the FCR write to be ignored, and the PROGE bit to be set.
CMD: Command
This field defines the flash command. Issuing any unused command will cause the Program-
ming Error flag to be set, and the corresponding interrupt to be requested if the PROGE bit in
FCR is set.
