Hi Originator;

If all you want to do is simultaneous alternating phase clocking on two channels, it takes a loop of only two instructions consuming four clock cycles, and the SX family can easily do that at speeds up to 12.5 MHz (80 nano seconds on and 80 off) with a 50 mHz resonator. Using the internal 4 mHz oscillator, the best you can get is 1 MHz (1 micro second on and 1 off).

As for slower; with a down counter you could program it to do almost any loop multiple slower.

Cheers,

Peter (pjv)
