C6472 SRIO interrupt rate control

Hello,


I'm attempting to lower the overhead on my SRIO Messaging ISR byt bulk processing input messages. I thought all that was necessary to do so was setting the INTDSTn_RATE_CNTL register to some value greater than 1. As a test I set the value to 2, and I am still getting an interrupt on every message which is received, not every other as I was expecting.


Thanks
