Each descriptor can be configured to allow one of four types of access privilege for the defined
memory region
— Bus master has full access (read, write and execute enabled)
— Bus master can read and execute (write illegal)
— Bus master can read and write (execution illegal)
— Bus master can only read (write and execution illegal)
Accesses to memory not covered by any protection descriptor will cause an access violation
