Hi, Can someone tell me if it's possible to use some bits of GPIOA when accessing data on the external data bus of the 56F805? The reason is that I already use the data bus and control lines /DS and /WR to put data on a latch. Since I don't use any address decoder, I want to know if I can use GPIOA as an I/O port or I'm stuck with an unused 16 bit address bus. Regards Bruno ------- Bruno Tremblay, Ing/Eng stag Gentec Inc.
