13.7 H2PB Exempt Main Regions

The Secure vs Non-Secure partitioning of the H2PB0/1/2 memory space is done in the H2PB bridge through the NONSEC registers. The partitioning is done peripheral by peripheral, bridges included. Each peripheral can be configured as Secure or Non-Secure, except PORT and EIC which can be configured as Mix-Secure or Non-Secure. This configuration only concerns PIC32CMSG devices and is done through the BOOTCFG fuses and applied by the Rom code.
