EEPROM-1 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.
5.6.2 EEPROM-1 Array Configuration Register
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.
Address: $FE1F

Bit 7:5 — Unused Bits
These read/write bits are software programmable but have no
functionality.
EEPRTCT — EEPROM-1 Protection Bit
The EEPRTCT bit is used to enable the security feature in the
EEPROM-1 (see EEPROM-1 Program/Erase Protection on page
63).
1 = EEPROM-1 security disabled
0 = EEPROM-1 security enabled
This feature is a write-once feature. Once the protection is enabled it
may not be disabled.
