EERA — EEPROM redundant array
This programmable/erase/read bit in EENVR and read-only bit in
EEACR configures the array in redundant mode. Reset loads EERA
from EENVR to EEACR.
1 = EEPROM array is in redundant mode configuration
0 = EEPROM array is in normal mode configuration
CONx — MCU configuration bits
These read/write bits can be used to enable/disable functions within
the MCU. Reset loads CONx from EENVR to EEACR.
CON2 — Unused
CON1 — Unused
CON0 — EEPROM security
1 = EEPROM security disabled
0 = EEPROM security enabled
