Figure 6-10. CFM Data Access Register (CFMDACC)
Supervisor address space assignment. The SUPV[31:0] bits are always readable
and only writable when LOCK = 0. Each Flash logical sector can be mapped into
supervisor or unrestricted address space. CFMSACC uses the same
correspondence between logical sectors and register bits as does CFMPROT. See
Figure 6-8
When a logical sector is mapped into supervisor address space, only CPU
supervisor accesses will be allowed. A CPU user access to a location in supervisor
address space will result in a cycle termination transfer error. When a logical sector
is mapped into unrestricted address space both supervisor and user accesses are
allowed.
1 Logical sector is mapped in supervisor address space.
0 Logical sector is mapped in unrestricted address space.
Data address space assignment. The DATA[31:0] bits are always readable and only
writable when LOCK = 0. Each Flash logical sector can be mapped into data or
both data and program address space. CFMDACC uses the same correspondence
between logical sectors and register bits as does CFMPROT. See
details.
When a logical sector is mapped into data address space, only CPU data accesses
will be allowed. A CPU program access to a location in data address space will
result in a cycle termination transfer error. When an array sector is mapped into
both data and program address space both data and program accesses are
allowed.
1 Logical sector is mapped in data address space.
0 Logical sector is mapped in data and program address space
