ENABLE_INTR:
Enable Interrupt on Protected Memory Region Violation
(EnablePMRInt): When set, the BUnit will latch violation information into this register
and send an interrupt request (opcode 0x70) to the PUnit. This bit is cleared upon
triggering and must be reset by software in order to trigger again. Memory protection is
maintained even while the interrupt/capture mechanism is disabled. It is used to enable
software debug of IMR errors, and is not expected to be used in end-user systems
