EESWAI — EEPROM Stops in Wait Mode
The EESWAI bit should be cleared if the WAIT mode vectors are
mapped in the EEPROM array.
PROTLCK — Block Protect Write Lock
EERC — EEPROM Charge Pump Clock
Prevents accidental writes to EEPROM. Read anytime. Write anytime if
EEPGM = 0 and PROTLCK = 0.
SHPROT — SHADOW Byte Protection
BPROT[4:0] — EEPROM Block Protection
Read and write anytime.
Read anytime. Write once in normal modes (SMODN = 1), set and
clear any time in special modes (SMODN = 0).
Read and write anytime.
