Digital loopback of codec AD50 on C5402 DSK - Wei Wen Dai - Dec 28 0:45:00 2000

Hi, I am programming the codec AD50 onboard the C5402DSKplus now. I could write to the codec registers correctly by a series of primary and secondary communications. With diffrent control words, I could change the gains and the sampling rate. However, once the digital loopback is enabled by setting to 1 the bit1 in register 1, no further control words can be written into the codec control registers. That's to say, once digital loopback is enabled, one can't change the codec configuration anymore, even by software resetting. The only way is to perform a hardware reset. Has anyone encountered similar problem ? Thank you. Dww |
