Those timings are only a starting point anyway, since actual performance is also dependent on the interface hardware you have. If you have an inverting optoisolator, you will (or won't) have to invert the pin. Same thing for inverting/noninverting buffers. Optos are also likely to change the timing, since they don't always have symmetric turn-on/turn-off times. - Steve ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
