We're developing a driver for the SJA1105. The DESTPORTS sometimes reads 0 with devices attached. Most of the time DESTPORTS reads correctly. The MAC addresses look fine.

Just wanted to ask if there's a scenario for DESTPORTS being = 0 when a device is attached that we are talking to?

Thanks,

-Rich
