Connecting to SyncSerial-Interface



Hello!

Im trying to connect a Siemens PSB2165 (ISDN Audio-Chip) to the
SyncSerial-Interface of the Etrax 100LX.

Ive activated the Syncserial-Port 3 and loaded the Device-Driver. Now I can
measure some Clock- and AC-Signals on the 8pin-Port next to the LEDs.

The Audio-Chip has
- a pin for the Serial Interface (bidirektional)
- a pin for clock (512kHz)
- a pin for Frame-Clock (8kHz)

My question now is where/how to connect these pins to the Etrax-Board. The
pinout-description is not very helpful.

Thanks for your help
Markus
