Small block data space. Each small array block of the UC3F EEPROM may be mapped into data
or both data and instruction address space. When a small array block is mapped into data
address space, SBDATA[M] = 1, only data accesses will be allowed. When a small array block
is mapped into both data and instruction address space, SBDATA[M] = 0, both data and
instruction accesses will be allowed.
If SBEN[M] = 0, the corresponding small block M is logically part of the host block and
SBDATA[M] has no effect. Instead, the corresponding DATA[M] bit will be used to determine if
the small block is mapped to Data or to both Data and Instruction address space.
Like the DATA bits, the SBDATA bits are not actually used in the UC3F EEPROM module but are
used by the BIU to determine access restrictions to the UC3F array. Block addresses are
decoded in the BIU to determine which small array block is selected, and the selected small
block’s SBDATA bit is compared with the address space attributes to determine validity of an
array access.
0 small block M is placed in both Data and Instruction address spaces
1 small block M is placed in Data address space
Small block protect. Each small block of the UC3F EEPROM can be individually protected from
program or erase operation. The UC3F will perform all program and erase interlocks and even
complete the program or erase sequence, but the program and erase voltages are not applied
to locations within the protected small block(s).
0 small block M is unprotected
1 small block M is protected
Reserved
BIU configuration bits. These register bits are reserved for BIU functionality and are strictly
outputs from the UC3F EEPROM.
Memory size. The MEMSIZ field is used to indicate the UC3F array size. The MEMSIZ bits are
read only and writes have no effect.

The Flash module on the MPC563 is 512 Kbytes.
Block size. The BLK bit is used to indicate the array block size used in the UC3F array. The BLK
bit is read only and writes have no effect.
0 array block size is 32 Kbytes
1 block size is 64 Kbytes NOTE: All blocks are 64 Kbytes (i.e. BLK is always set)
Array address mapping. The MAP bit is used to indicate the UC3F array address mapping within
a 2
useful when the UC3F array is a non-2
When MAP = 0, the UC3F array is mapped to the bottom (starting at address 0) of the 2
in which the array resides. For modules with 2
When MAP = 1, the UC3F array is mapped to the top (ending at address all $F’s) of the 2
in which the array resides.
0 UC3F array is mapped to bottom of 2
1 UC3F array is mapped to top of 2
