        The number of MPU regions supported by the target MCU. The common value
        for Cortex-M4/M7/M33 is 8, but some MCUs expose 4, 12, or 16 regions.
        Set this to the actual value reported by the hardware, otherwise the MPU
        initialization will reject the configuration at runtime.
