Group of Channels, Permission Definition Register
The permission definition registers are valid only for the group of channels operating in MPU mode. This is the case
if MPE is set to '1'. If the group does not operate in MPU mode, the permission configuration is not required (don't
care).
Normally MPU channels operate in range mode for the address definitions.
The type of the permission, which could be set-up, depends on the comparator type configuration (CTC) for each
comparator pair. MPU channels could be configured either to check instruction addresses (IA) or operand address-
es (OA). IA ranges could be used to define exceute permissions. OA ranges could be used to define read and write
permissions.
The comparator type for MPU usage could be set to
• CTC=0: both IA ranges define execute permissions,
• CTC=1: both OA ranges define read/write permissions and
