Dear sir,

I am working in a project which need to setup a 8051 Dial circuit.
The chips Mt8888 is expected to be involved in the project.
As I am new to telephone related and i have gone through the MT8888 data
sheet.
However, i still feel that it is quite difficult to me.
Are there Any DTMF referance material and C Code example for MT8888?

any comment and advice would be great to me.

many thx.
