Table 6-2. FLASHBAR Field Descriptions
Table 6-3. CFM Register Address Map
Base address field. Defines the 0-modulo-512K base address of the Flash
module. By programming this field, the Flash may be located on any 512Kbyte
boundary within the processor’s four gigabyte address space.
Reserved, should be cleared.
Write protect. Read only. Allows only read accesses to the Flash. This bit is
always set and any attempted write access will generate an access error
exception to the ColdFire processor core.
0 Allows read and write accesses to the Flash module
1 Allows only read accesses to the Flash module
Reserved, should be cleared.
Address space masks (ASn).
These five bit fields allow certain types of accesses to be “masked,” or inhibited
from accessing the Flash module. The address space mask bits are:
C/I
SC Supervisor code address space mask
SD Supervisor data address space mask
UC User code address space mask
UD User data address space mask
For each address space bit:
0 An access to the Flash module can occur for this address space
1 Disable this address space from the Flash module. If a reference using this
These bits are useful for power management as detailed in
Management.”
Valid. When set, this bit enables the Flash module; otherwise, the module is
disabled.
