Our embedded controller is based on Renesas RH850 / U2A16 Microcontroller.  Our controller has Two of these microcontrollers.  The Two microcontrollers communicate with each other over full-duplex Renesas High Speed Serial Interface(RHSIF).  This interface is based on IEEE 1596.3-1996 reduced range link LVDS IOs.
Is this interface required to have the ability to detect bus off?  Bus off could happen due to a physical disconnect of the RHSIF wires or if the wires were shorted to each other or shorted to ground or Vcc.
