MPC (Memory Protection Controller)

General Description

MPC is a Memory Protection Controller which helps in configuring the memory as secure or non-secure.

MPC provides the following functionality:

1. Allocates PCs (Protection Contexts) run-time memory separation/ isolation and sharing.

2. An ARMv8-M TrustZone-M compliant memory protection controller between Secure and Non-Secure worlds (S-MPC and NS-MPC) and make the memory accessible and visible either in its Secure address alias or its Non-Secure address alias.

   For S-MPC, any Non-secure access targeting this region is blocked. The S-MPC controls Secure access targeting this region.

   For NS-MPC, any Secure access targeting this region is blocked. The NS-MPC controls Non-secure access to this region.

3. Breaks down the memory space into fixed-sized blocks/pages and the MPC configures the attributes of each block for all PCs.

   Block size is design-time configurable and is recommended at 4KB.

The functions and other declarations used in this driver are in cy_mpc.h. You can include cy_pdl.h (ModusToolbox only) to get access to all functions and declarations in the PDL.

You can use this driver to configure memory regions as secure/non-secure.
