User Configuration Fuses
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.

User Configuration Fuse Definitions
(3)
The AT89LP213/214 includes 19 user fuses for configuration of the device. Each fuse is
accessed at a separate address in the User Fuse Row as listed in
by programming 00h to their locations. Programming FFh to 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.
