space of the MCU. The starting address of the array is determined by the CFM array base address which
must reside on a natural size boundary; that is, the CFM array base address must be an integer multiple of
the array size. The CFM register space must reside on a 64 byte boundary as determined by the CFM
register base address.
form a contiguous non-volatile memory space. Each pair of 32-bit blocks (even and odd) interleave every
4 bytes to form a 256-Kbyte section of memory.
The CFM module has hardware interlocks to protect data from accidental corruption. The <<BLOCK
NAME>> memory array is logically divided into 16-Kbyte sectors for the purpose of data protection and
access control. A flexible scheme allows the protection of any combination of logical sectors (see
Section 6.3.4.4, “CFM Protection Register
supervisor/user and program/data space access to these sectors.

The CFM on the MCF5281 and MCF5214 is constructed with four banks of
32K x 16-bit Flash arrays to generate 256 Kbytes of 32-bit Flash memory.
