The SUPV[15:0] bits are always readable and only writable when
LOCK = 0. Each FLASH logical sector can be mapped into supervisor
or unrestricted address space. SGFMSACC uses the same
correspondence between logical sectors and register bits as does
SGFMPROT. See
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.
