MC68HC912DT128A — Rev 4.0 Technical Data

MOTOROLA EEPROM Memory 129

FPOPEN — Opens the Flash Block for Program or Erase

0 = The whole Flash array is protected.

1 = The whole Flash array is enable for program or erase.

Loaded from SHADOW word at reset. Read anytime. Write anytime

in special modes (SMODN=0). Write once ’0’ is allowed in normal

mode.

EESWAI — EEPROM Stops in Wait Mode

0 = The module is not affected during WAIT mode

1 = The module ceases to be clocked during WAIT mode

Read and write anytime.

NOTE: The EESWAI 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).
