EEPROM-2
Functional Description
EERA — EEPROM Redundant Array Bit
This programmable/erasable/read bit in EENVR2 and read-only bit in
EEACR2 configures the array in redundant mode. Reset loads EERA
from EENVR2 to EEACR2.
1 = EEPROM array is in redundant mode configuration.
0 = EEPROM array is in normal mode configuration.
CON2 and CON1 — MCU Configuration Bits
These read/write bits can be used to enable/disable functions within
the MCU. Reset loads CONx from EENVR2 to EEACR2.
NOTE: The EEPROM protect feature is a write-once feature. Once the
protection is enabled, it may not be disabled.
EEPRTCT — EEPROM Protect Bit
This one-time programmable bit can be used to protect 16 bytes
($6F0–$6FF) from being erased or programmed.
1 = EEPROM protect disabled
0 = EEPROM protect enabled
EEBP3–EEBP0 — EEPROM Block Protection Bits
These read/write bits select blocks of EEPROM array from being
programmed or erased. Reset loads EEBP3–EEBP0 from EENVR2
to EEACR2.
1 = EEPROM array block is protected.
0 = EEPROM array block is unprotected.
