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.
Sensing a permanent dominant condition for a timeout period.
Receiver switches to single ended on CANH.
CANL and RTL are both switched off (high impedance) and transmission continues on CANH 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 CANH and CANL (pulse count = 4).
Receiver remains in differential mode. No received data lost.
RTH remains on and CANH remains enabled.
Recovery is provided, sensing the edge-count difference between CANH and CANL after the detection of four
consecutive pulses.
Detected by a comparator for CANL > 7.3V after a timeout period.
Receiver switches to single ended on CANH after timeout.
RTL is switched off after timeout. CANH remains active.
Sensing CANL < 7.3V after the timeout period.
Sensing a permanent dominant condition on the differential comparator (CANH - CANL > -3.2V) for the timeout
period.
Receiver switches to CANH single-ended mode after timeout.
CANL and RTL are both switched off after timeout. Transmission remains ongoing on CANH.
When the short is removed, the recessive bus voltage is restored (RTL on if CANH - CANL < -3.2V) but CANL still
remains disabled and ERR = 0. If the differential voltage remains below the recessive threshold level (CANH -
CANL < -3.2V) for the timeout period, reception and transmission switch back to the differential mode.
