Anyway, I don't think it's any harder in either direction. Create a 5-bit 32 MHz counter, which is reset by falling edge of PHI2 incoming from motherboard. Then output 0 if the counter has value 31 or 0-14, 1 otherwise (if you wanted to shift in other direction, you would output 0 for values 1-16). Regards, Michau.
