 		 #121912 - mode 2
Responding to: ???'s previous message
The OP said:
I wish to create a pulse with frequency = 3.6864MHz/2

That's CCLK(=7.3728MHz)/4. Timer0 in mode2 reloading TH0=0FFh would overflow at each PCLK, that's CCLK/2. If it toggles the output, it's CCLK/4.

However, the trick with CLKOUT is valid for the 3.6xxxMHz output.
