Digital loopback of codec AD50 on C5402 DSK

Started by Wei Wen Dai December 28, 2000

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

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
