UPP Interface Programming

Paul Joseph
Expert 2795 points

I am programming UPP interface for chip C6748. To make it work,  need to program programmable multiplexer on the chip.

The example,  I have shows how to program it loopback mode without any coonections to pinout.

I need to connect the UPP interface at list port A to external connections to read data by this port.

Please let me know and thanks!

    Have you tried the Pin Multiplexing Utility? This should help you correctly configure the chip to connect the UPP interface externally.

    One other question:

    I have raw event setting a bit when interrupt on EMAC or UPP happened (C6748). I am also programmed hardware interrupt and event interrupt handler.

     Unfortunately I able to service interrupt only polling raw or masked interrupt register.

    It does not happened on CPU with some reasons I don't understand.
    I correctly programmed all event, mask, clear registers in event module(Megamodule).

    For EMAC it events 27 and 31, for UPP it event 94. I programmed interrupts INT5,INT6,INT7 on processor as an entry points to interrupt routine.
    Can you please advice?
