This bit should be cleared if the wait mode vectors are mapped in the EEPROM array.
Read anytime. Write once in normal modes (SMODN = 1), set and clear any time in special modes
(SMODN = 0).
Read and write anytime.
Prevents accidental writes to EEPROM. Read anytime. Write anytime if EEPGM = 0 and PROTLCK = 0.

0 = Module is not affected during wait mode
1 = Module ceases to be clocked during wait mode
0 = Block protect bits and bulk erase protection bit can be written
1 = Block protect bits are locked
0 = System clock is used as clock source for the internal charge pump. Internal RC oscillator is
1 = Internal RC oscillator drives the charge pump. The RC oscillator is required when the system
stopped.
