User Configuration Fuses
The AT89LP428/828 includes 11 user fuses for configuration of the device. Each fuse is
accessed at a separate address in the User Fuse Row as listed in Table 23-6. Fuses are cleared
by programming 00H to their locations. Programming FFH to a fuse location will cause that fuse
to maintain its previous state. To set a fuse (set to FFH), the fuse row must be erased and
then reprogrammed using the Fuse Write with Auto-erase command. The default state for all
fuses is FFH.
Notes:
1. The default state for all fuses is FFH.
2. Changes to these fuses will only take effect after a device POR.
3. Changes to these fuses will only take effect after the ISP session terminates by bringing RST high.
