I don't understand exactly what you're trying to do, but it sounds like
you should be using flag pins instead of the external port. Have you
read the Hardware Reference Manual?

Watch for word wrap in that link. The external port is covered in
chapter 7. The flag pins are in chapter 13.

Hello!
I am a student of the TGM a technical college in Vienna.
I use the ADSP 21161N_ez_kite_lite board with a SHARC processor. I
need help because I want to receive some signals (HIGH/LOW) from an
external board which is connected to a port from the DSP. The signals
will be used by the application.
I have problems to address each bus-line from the port separate. I
tried this by the external port 9 which I prefer, but with no success.
An interrupt-routine should receive the signals. The timer and his
interrupt are programmed successfully by me.
I need this for my project which I need to get my graduation
certificate from high school.
Please help me!
Regards
Christian
