EEPROM Control Registers
MC68HC912D60A — Rev. 3.1 Technical Data
Freescale Semiconductor EEPROM Memory 111
FPOPEN — Opens the Flash Block for Program or Erase
0 = The whole Flash array (32-Kbyte and 28-Kbyte) is protected.
1 = The whole Flash array (32-Kbyte and 28-Kbyte) 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).
DMY— Dummy bit
Read and write anytime.
