port writing

port writing

2005-04-05 by Gennady Palitsky

Hi all,
is there a way to move a byte from flash to the i/o port ?
as far as i understand, using IOSET, IOCLR 1)requires at least one extra 
cycle, 2)can give incorrect port value after IOSET and before IOCLR.
is there better way to do it?

The Philips docs tell to write to IOPIN directly in this case.
