Flash General-purpose NVM Commands
In the same way, the Clear Lock command (CLB) is used to clear lock bits.
Table 20-11. 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 20-12. 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. The general-purpose NVM bit is deactivated when the corresponding bit in the pattern value
is set to 1.
Table 20-13. Set/Clear GP NVM Command
General-purpose NVM bits can be read using the Get GPNVM Bit command (GGPB). The n
GP NVM bit is active when bit n of the bit mask is set..
