Can someone please explain to me HOW the following is used in the HUA demo for C6678

I am using:

CCS5.5.0.00077

mcsdk_2_01_02_06

bios_6_35_04_50

* Enable Event Groups here and registering of ISR for specific GEM INTC is done using EventCombiner_dispatchPlug() and Hwi_eventMap() APIs

Ecm.eventGroupHwiNum[0] = 7;

Ecm.eventGroupHwiNum[1] = 8;

Ecm.eventGroupHwiNum[2] = 9;

Ecm.eventGroupHwiNum[3] = 10;

I understand the CIC and the event combiner, but not sure how the above code is used in this demo and where the events are being mapped to interrupts.

Hi Murad,
Thank you for the post. I will check with BIOS experts and get back to you on this. Thank you for your patience.

The 4 statements you mentioned above basically are mapping the combined events (0, 1, 2, and 3) into interrupt vectors 7, 8, 9, and 10 respectively.

Without knowing what the program is doing, I cannot speak to what actual events are being routed into the combined events.

One thing you can to is...if you are in CCS and open up the Tools->ROV. It can show you a list of Hwi and EventCombiner that have been setup.

Thank you Judah for your reply...This is from the HUA Demo that used with C6678 EVM...all related info are listed in my first post above...I understand the CIC and event combiner, but not sure why they are used in this HUA project?!

Murad,

I'm not familiar with that demo so I do not know the details of how or if the event combiner is used. Perhaps its just setup and not used at all?

Again, if you are in a CCS environment, you can use the ROV tool to determine what Hwis and What Events in the EventCombiner have been enabled.

Thank you Judah,
The ROV revealed that eventId 48 is associated with EmacRxPktISR...I was able to find some help at the following link:
