Section 18 Controller Area Network (HCAN) [H8S/2556 Group]
IRR0 Clearing: The reset interrupt flag (IRR0) is always set after a power-on reset, recovery
from software standby mode and watch mode, or canceling module standby mode. As an HCAN
interrupt is initiated immediately when interrupts are enabled, IRR0 should be cleared.
