Figure 11 EEPROM Block Protect Mapping
8.2 EEPROM Control Registers
NOSEC — No Security Mode
0 = Security Mode will be enabled on the next reset
1 = Normal Operation
This bit should be 1 for normal operation. Please contact Motorola Marketing for the security mode op-
eration.
EESWAI — EEPROM Stops in Wait Mode
0 = Module is not affected during wait mode
1 = Module ceases to be clocked during wait mode
This bit should be cleared if the wait mode vectors are mapped in the EEPROM array.
PROTLCK — Block Protect Write Lock
0 = Block protect bits and bulk erase protection bit can be written
1 = Block protect bits are locked
Read anytime. Write once in normal modes (SMODN = 1), set and clear any time in special modes
(SMODN = 0).
EERC — EEPROM Charge Pump Clock
0 = System clock is used as clock source for the internal charge pump. Internal RC oscillator is
stopped.
1 = Internal RC oscillator drives the charge pump. The RC oscillator is required when the system
bus clock is lower than fPROG.
Read and write anytime.
