Now we are back to, why is your system different? What is triggering a
collision for you, but not Parthiban?
There is nothing in the standard about reporting a collision. So this
is a Microchip extension? So the framework is not doing anything when
it happens, which will explain why it becomes a storm.... Until we do
have a mechanism to handle vendor specific interrupts, the frame work
should disable them all, to avoid this storm.
Does the datasheet document what to do on a collision? How are you
supposed to clear the condition?
