I'm trying to use a flip-flop in a GAL22V10 and am having problems with making it do what I want. The output cell on a 22V10 basically is a D flip-flop with asynchronous reset, and synchronous preset, which seems straightforward enough. Unfortunately it doesn't seem to be working the way I'd expect..... So, I went looking for some documentation... which I sure haven't been able to find. I'm sure I'm making some incorrect assumption about this particular D flip-flop, but without docs it's proving difficult to figure out. Is someone aware of a truth table or similar for the output register on a 22V10?
