Flash Lock Commands
Flash General-purpose NVM Commands
All lock regions must be unlocked before the Full Erase command by using the CLB command.
Otherwise, the erase command is aborted and no page is erased.
Table 14-9.
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. A Bit Mask is pro-
vided as argument to the command. When bit 0 of the bit mask is set, then the first lock bit is
activated.
In the same way, the Clear Lock command (CLB) is used to clear lock bits. All the lock bits are
also cleared by the EA command.
Table 14-10. Set and Clear Lock Bit Command
Lock bits can be read using Get Lock Bit command (GLB). The n
n of the bit mask is set..
Table 14-11. Get Lock Bit Command
General-purpose NVM bits (GP NVM bits) can be set using the Set GPNVM command (SGPB).
This command also activates GP NVM bits. A bit mask is provided as argument to the com-
mand. When bit 0 of the bit mask is set, then the first GP NVM bit is activated.
In the same way, the Clear GPNVM command (CGPB) is used to clear general-purpose NVM
bits. All the general-purpose NVM bits are also cleared by the EA command. The general-pur-
pose NVM bit is deactivated when the corresponding bit in the pattern value is set to 1.
