19.2 Programming Model
19.2.1 CMF EEPROM Control Registers
MPC555
USER’S MANUAL
The CMF EEPROM Module consists of two addressed sections. The first is the 32-
byte control registers used to configure, program, erase and test the CMF EEPROM
array while, the second is the array.

The control registers are used to control CMF EEPROM module operation. They re-
side in supervisor data space. On master reset the registers are loaded with default
reset information. Some of the registers are special CMF NVM registers which retain
their state when power is removed from the CMF EEPROM. These special FLASH
NVM registers are identified in the individual register field and control bit descriptions.
The CMF EEPROM control registers are accessible for read or write operation at all
times while the device is powered up except during master reset, soft reset or erase
interlock write.
The access time of a CMF register is one system clock for both read and write access-
es. Accesses to reserved registers will cause the BIU to generate a data error excep-
tion.
