AT91SAM9XE128/256/512 Preliminary
Flash Full Erase Command
Flash Lock Commands
Flash General-purpose NVM Commands
This command is used to erase the Flash memory planes.
All lock bits must be deactivated before using the Full Erase command. This can be done by
using the CLB command.
Table 14-21. Full Erase Command
Lock bits can be set using WPL or EWPL commands. They can also be set by using the Set
Lock command (SLB). With this command, several lock bits can be activated at the same time.
Bit 0 of Bit Mask corresponds to the first lock bit and so on.
In the same way, the Clear Lock command (CLB) is used to clear lock bits. All the lock bits can
also be cleared by the EA command.
Table 14-22. Set and Clear Lock Bit Command
Lock bits can be read using Get Lock Bit command (GLB). When a bit set in the Bit Mask is
returned, then the corresponding lock bit is active.
Table 14-23. Get Lock Bit Command
General-purpose NVM bits (GP NVM) can be set with the Set GPNVM command (SGPB). Using
this command, several GP NVM bits can be activated at the same time. Bit 0 of Bit Mask corre-
sponds to the first GPNVM bit and so on.
In the same way, the Clear GPNVM command (CGPB) is used to clear GP NVM bits. All the
general-purpose NVM bits are also cleared by the EA command.
