Hello all,
now I have developed a high speed 24 bit Counter.
I use a Atmel 8252 with timer 0 and 1 in 16 bit external countermode. I use an external highspeed counter to divide the first 8 bit.
The last bit (7) is connected to the T0 or T1 input pin.

But my great Problem is the counter from the Atmel works wrong.????
It increase on a rising edge or on a falling edge. The datasheet from Atmel decribes nothing..... But in the original Intel datasheet it is defined on falling edge.

What can i do ???
