I want to use the Non-PCM detecion to detect whether the DIR port have normal audio data, if No, PCM9211 can give a signal to MCU so that mcu can control the system to be in standby mode. 

    My question is How to configurate the register , which register will give the INT signal to MCU?  I have try to configurate 20h, 25h, 26h,28h,2Ah,2bh,  but I can't get any change at pin  INT0 & INT1. pls. give some help to me . thanks
