[A89] _rowread
Hi, I'm having some trouble getting _rowread
to work accurately and I wonder if any of
you could tell me why.
First I set AUTO_INT_1 to DUMMY_HANDLER.
Then I use the following:
while (!(_rowread(0x00FE)&0x0021))
to make a loop that executes until the shift
key is pressed.
The problem is that the loop also exits when
the up key is pressed.
Why?
