Interrupt HPI in non-multiplex mode - LindaHYang - Jan 22 0:37:00 2003



Hi there,

I am trying to find out how to interrupt DSP Host-Port-Interface in
non-multiplex mode for C542x DSPs.

HPIC is memory-mapped to address 2C. In non-multiplex mode, is it
possible to read and/or write to HPIC or there is some other way to
cause interrupt?

Thanks in advance!

Linda
