19.3.1 Address Range of Shadow Information
19.3.2 Reset Configuration Word (CMFCFIG)
MPC555
USER’S MANUAL
The address range of the shadow information is the entire address range of the CMF
EEPROM array but the high order array addresses, ADDR[14:23], are not used to en-
code the location. The first 16 bytes (ADDR[24:29] = 0x00 to 0x0F) of the 256 bytes of
shadow locations are withheld by Motorola for the reset configuration word and future
applications. The remaining 240 bytes are available as supervisor data. This is shown
in
The CMF EEPROM reset configuration word is implemented in the first word (AD-
DR[24:29] = 0x00) of the special shadow locations. The reset configuration word along
with the rest of the shadow information words is located in supervisor data address
space. The purpose of the reset configuration word is to provide the system with an
alternative internal source for the reset configuration.
Note that with the exception of bit 20, the bits in the CMFCFIG are identical to those
in the USIU hard reset configuration word. Refer to

19-2.
When SIE = 1, only program page buffer zero can be programmed.
All programming writes to the CMF will be directed to program page
buffer 0 if SIE = 1. In addition, the other program page buffers cannot
be accessed and will not apply any programming voltages to their
CMF array blocks while programming the shadow information.
