Sensing a permanent dominant condition on CANH for a timeout period.
Receiver switches to single ended on CANL.
CANH and RTH are both switched off (high impedance) and transmission continues on CANL after timeout.
When the short is removed, the recessive bus voltage is restored. If the differential voltage remains below the
recessive threshold level for the timeout period, reception and transmission switch back to the differential mode.
Detection is provided, sensing the pulse-count difference between CANL and CANH (pulse count = 4).
Receiver remains in differential mode. No received data lost.
Driver remains in differential mode. No transmission data lost.
Recovery is provided, sensing the pulse-count difference between CANL and CANH after the detection of four
consecutive pulses.
