User Configuration Fuses
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 Table 23-5. Fuses are cleared
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.
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.
4. AIN0 (P1.0) and AIN1 (P1.1) always reset to input-only mode. SS (P1.4) always resets to quasi-bidirectional mode.
