EEPROM-2 Register Descriptions
NOTE:
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.
6.6.2 EEPROM-2 Array Configuration Register
The EEPROM-2 array configuration register configures EEPROM-2
security and EEPROM-2 block protection.
This read-only register is loaded with the contents of the EEPROM-2
non-volatile register (EE2NVR) after a reset.
Address: $FF7F

Bit 7:5 — Unused Bits
These read/write bits are software programmable but have no
functionality.
EEPRTCT — EEPROM-2 Protection Bit
The EEPRTCT bit is used to enable the security feature in the
EEPROM-2 (see EEPROM-2 Program/Erase Protection on page
83).
1 = EEPROM-2 security disabled
0 = EEPROM-2 security enabled
This feature is a write-once feature. Once the protection is enabled it
may not be disabled.
