19.2.2.4 Array Configuration for CMF Module B
19.3 Shadow Information
MPC555
USER’S MANUAL
Programming the shadow information uses the same procedure as programming the
array, except that there are only 256 bytes available in the shadow row. Before starting
the program sequence SIE must equal one.
The SIE bit is write protected by the SES bit for programming operation. Writes will
have no effect if (SES = 1 and PE = 0). The SIE bit can be read whenever the registers
are enabled.
When SIE = 1, normal array accesses are disabled and the shadow information is en-
abled. When an array location is read using supervisor data in this mode, the shadow
information is read from a location determined by the column, 32-byte read page select
and read page word addresses (ADDR[24:29]) of the access. Accessing the CMF con-
trol block registers accesses the registers and not the shadow information. The read
page buffer address monitor is reset whenever SIE is modified, making the next CMF
array access an off-page access.
The default reset state of SIE is normal array access (SIE = 0).

1. If SIE=1, then the shadow row is enabled instead of the flash block.
Locations 0x4 00000 to 0x4 000F of the shadow row are Reserved by
Motorola for possible future use.
