BUS(+)’s short circuit to GND
BPG flag is set.
Clear processing of BPG flag
BPG flag is set.
BUS(–)
BUS(+)
Bus input is switched to BUS(–) only.
At bus idle status, when BUS(+) is short-circuited to GND, it is also detected and processed by the same way as the
case of the BUS(–)’s short circuit to V
DD as stated above.

At the bus idle status, when BUS(+) is short-circuited to V
DD, the input of LAN bus is switched to communicate
normally by detecting the BUS(+)’s short circuit to V
DD through the same flow as the case of the BUS(–)’s short
circuit to GND as stated above.
When BUS(+) returns to the normal status, the inputs of both BUS(+) and BUS(–) are switched as reception inputs
and the reception status of a normal LAN bus is given as before. If BPV flag is then cleared, all interrupt requests
on LAN bus are cleared.
