Operating Modes and On-Chip Memory
4.8.1.2 Block Protect Register
Technical Data
96
Address: $0035
This register prevents inadvertent writes to both the CONFIG register
and EEPROM. The active bits in this register are initialized to 1 out of
reset and can be cleared only during the first 64 E-clock cycles after
reset in the normal modes. When these bits are cleared, the associated
EEPROM section and the CONFIG register can be programmed or
erased. EEPROM is only visible if the EEON bit in the CONFIG register
is set. The bits in the BPROT register can be written to 1 at any time to
protect EEPROM and the CONFIG register. In test or bootstrap modes,
write protection is inhibited and BPROT can be written repeatedly.

The functionality of LVPEN/LVPI was changed from earlier versions
of the M68HC11K Family. Setting this bit has no effect on the LVPI bit
in the PPROG register.
