Hello,
My customer has I2C communication problem of CDCM6208 on already released product. The device intermittently (about 1/200) fails to accept initial setting.
The system writes the setting from register 0 to 20, and hangs up after regisiter3 write because CDCM6208 hold “NAK” signal. This hang up always happen for register 3 access when the problem happen. And the problem cannot be observed if the customer changes the register writing order (for example Regster3 -> Regster0 -> Register1 ….)
Have you ever experienced this kind of problem? Or the device have access limitation potentially?
Best regards,
Tetsuro
