5.6.2 EEPROM-1 Array Configuration Register
MC68HC08AZ60A — Rev 0.0
MOTOROLA
NOTE:
Address:
Writing logic 0s to both the EELAT and EEPGM bits with a single
instruction will clear EEPGM only to allow time for the removal of high
voltage.
The EEPROM-1 array configuration register configures EEPROM-1
security and EEPROM-1 block protection.
This read-only register is loaded with the contents of the EEPROM-1
non-volatile register (EE1NVR) after a reset.
Bit 7:5 — Unused Bits
EEPRTCT — EEPROM-1 Protection Bit
This feature is a write-once feature. Once the protection is enabled it
may not be disabled.
Reset:
Read: UNUSED UNUSED UNUSED EEPRTCT

Write:
These read/write bits are software programmable but have no
functionality.
The EEPRTCT bit is used to enable the security feature in the
EEPROM-1 (see
63).
1 = EEPROM-1 security disabled
0 = EEPROM-1 security enabled
