The Flash Controller must be unlocked using the Flash Control Register before program-
ming or erasing Flash memory. Writing the sequence
Control Register unlocks the Flash Controller. When the Flash Controller is unlocked,
Flash memory can be enabled for mass erase or page erase by writing the appropriate
enable command to the FCTL. Page erase applies only to the active page selected in Flash
Page Select Register. Mass erase is enabled only through the On-Chip Debugger. Writing
an invalid value or an invalid sequence returns the Flash Controller to its Locked state.
The write-only Flash Control Register shares its register file address with the read-only
Flash Status Register.
