CKIN becomes valid at this point

Using RESB

The KD16903 consists of an DSP Unit, Host Interface, and a Codec Interface. And between these internal units,

information is exchanged via the interrupt mechanism.

None of the internally exchanged informations are available outside the KD16903.

On the handphone, signals FS, MCLK, CKIN are controlable by the MSM. However, it is also likely that the

KD16903 may fall into a state of deadlock, since none of these signals are monitorable externally.
