Device Signature Imprint Table
Latching of Fuses
Table 19-5.
Notes:
Note that fuse bits are locked if Lock Bit 1 (LB1) is programmed. Fuse bits should be pro-
grammed before lock bits. The status of fuse bits is not affected by chip erase.
Fuse bits can also be read by device firmware. See section
Data from Software” on page
Fuse values are latched when the device enters programming mode and changes to fuse values
have no effect until the part leaves programming mode. This does not apply to the EESAVE
Fuse which will take effect once it is programmed. Fuses are also latched on power-up.
The device signature imprint table is a dedicated memory area used for storing miscellaneous
device information, such as the device signature and oscillator calibration data. Most of this
memory segment is reserved for internal use, as outlined in
Table 19-6.
