• Manufacturer: Renesas Electronics Corporation.

Bit 10—Remote Frame Request Interrupt Flag: Status flag indicating that a remote frame has
been received in a mailbox (buffer).
Bit 9—Receive Message Interrupt Flag: Status flag indicating that a mailbox (buffer) receive
message has been received normally.
Bit 8—Reset Interrupt Flag: Status flag indicating that the HCAN module has been reset. This
bit cannot be masked by the interrupt mask register (IMR). When this bit is not cleared after a
reset input or recovery from software standby mode, this bit executes the interrupt processing
immediately by enabling an interrupt by the interrupt controller.
Note: * After reset or hardware standby release, the module stop bit is initialized to 1, and so the
