Section 16 Controller Area Network (HCAN)
Bit 8—Reset Interrupt Flag (IRR0): Status flag indicating that the HCAN module has been
reset. This bit cannot be masked in the interrupt mask register (IMR). If this bit is not cleared after
reset input or recovery from software standby mode, interrupt handling will be performed as soon
as interrupts are enabled by the interrupt controller.
Note: * After reset or hardware standby release, the module stop bit is initialized to 1, and so the
Bits 7 to 5, 3, and 2—Reserved: These bits always read 0. The write value should always be 0.
Bit 4—Bus Operation Interrupt Flag (IRR12): Status flag indicating detection of a dominant bit
due to bus operation when the HCAN module is in HCAN sleep mode.
