Section 18 Controller Area Network (HCAN) [H8S/2556 Group]
HCAN sleep mode is entered by setting the HCAN sleep mode bit (MCR5) to 1 in the master
control register (MCR). If the CAN bus is operating, the transition to HCAN sleep mode is
delayed until the bus becomes idle.
Either of the following methods of clearing HCAN sleep mode can be selected:
