hi
I have written the following program for dsk6711 to use McBSP1 as
I/O; but when I debug the program by putting a break point at the
end or middle of the for loop,the content of input buffers (like
FSRP) don't change although I change the logical level of the
corresponding input pins. In other word the program read input pins
only once in my program. Why?
Also where can I find more information about DB_CTL0/1 on dsk6711
and the HDL code of its PAL22v10?
thanks
my program is:
