MODE
DESCRIPTION
Detection
Sensing a permanent dominant condition on CANH for a timeout period.
Receiver
Receiver switches to single ended on CANL.
Driver
CANH and RTH are both switched off (high impedance) and transmission continues on CANL after timeout.
Recovery
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.
MODE
DESCRIPTION
Detection
Detection is provided, sensing the pulse-count difference between CANL and CANH (pulse count = 4).
Receiver
Receiver remains in differential mode. No received data lost.
Driver
Driver remains in differential mode. No transmission data lost.
Recovery
Recovery is provided, sensing the pulse-count difference between CANL and CANH after the detection of four
consecutive pulses.

Conditions
Note: The RTH-pulldown current switch and the RTL-pullup current switch are closed in normal mode with or without fault conditions,
open in sleep mode.
