Flash Control Register shares its Register File address with the Read-only Flash Status
Register.
FCMD—Flash Command
73H = First unlock command.
8CH = Second unlock command.
95H = Page erase command.
63H = Mass erase command
5EH = Flash Sector Protect Register select.
* All other commands, or any command out of sequence, lock the Flash Controller.
The Flash Write Protect option bit is ignored
The Flash Sector Protect Register is ignored for programming and erase operations
Programming operations are not limited to the page selected in the Page Select
Register
Bits in the Flash Sector Protect Register can be written to 1 or 0
The second write of the Page Select Register to unlock the Flash Controller is not
necessary
The Page Select Register is written when the Flash Controller is unlocked
The Mass Erase command is enabled
