7.3 EEPROM Control Registers
7.3.1 EEPROM Module Configuration Register
M68HC12B Family — Rev. 8.0
MOTOROLA
This section describes the EEPROM control registers.
EESWAI — EEPROM Stops in Wait Mode Bit
PROTLCK — Block Protect Write Lock Bit
EERC — EEPROM Charge Pump Clock Bit
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 anytime
in special modes (SMODN = 0).
The RC oscillator is required when the system bus clock is lower than f
Read and write anytime.
Address: $00F0
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.
1 = Internal RC oscillator drives the charge pump.
