[oopic] Re: Angle of attack VII - any help appreciated

A more interesting solution uses a small CPLD. I have a development
board with a 44 pin Xilinx XC9572XL device so I created the circuit. A
single 4 bit loadable counter, an AND gate and a D flop take less than
10% of the macrocells. This leaves a lot of logic left for other
things.

FWIW, the chip is about the size of a dime. This particular device
uses 3.3V logic levels which can be a PITA. There is a regular XC9572
device for 5V logic and it is available in a PLCC 44 package. About
the size of a quarter.

I don't spend near enough quality time with my CPLDs and FPGAs. It was
an interesting diversion.
