Using GPIOA and data bus

Started by Bruno Tremblay August 12, 2003

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.
