Hi,
For the question 3, I suppose to find the answer. Secondary interrupt 112 is connected to the host interrut 8, meaning that CIC_OUT8 is used. We can confirm this by inspecting eventId value=104 returning from CpIntc_getEventId(8) function. In the .cfg file eventCombiner's 4 outputs is connected to the hwi pins 7,8,9 and 10.
To sum up;
SecondaryInt 112 -> HostInt8(CIC_OUT8) -> hwi pin 10 (104/32=3).
Is it correct?
