The SGFM Data Access Register (SGFMDACC) is banked and specifies
the data/program access permissions of FLASH logical sectors.

The DATA[15:0] 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. SGFMDACC uses the same
correspondence between logical sectors and register bits as does
SGFMPROT. See
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.
