digital input external interrupt setting in ucos II

Started by "yan...@omniverter.com [rabbit-semi]" December 21, 2016
Hello,

I am using BL4S200 and I use UCOS II to operate my program. I need scan 3 digital inputs to find up and down edge. I am able to set 2 channels, but as soon as I set the third one. I got run time error : set permission denied. Do you any body know what it is problem, and how to fix it. Thank you very much.
I have debuged the code. Error comes from the following notes:

"If DQE also in use OR settings require IIB, then set error"

does anybody know how to fix it?
