Understanding automatic pin selection in GPIF II Designer
I am building a FX3 to Compact Flash GPIF bridge. When changing from 8 bit to 16 bit data bus, the GPIO pins for the data and address bus change. Unfortunately, I do not under stand how to interpret GPIO46:28 for the address bus? Which pins are the address bus?
When configured as an 8 bit, the address bus is labeled GPIO8:13. So that means the address pins are GPIO 8, GPIO 9, GPIO 10, GPIO 11, GPIO 12 and GPIO 13.
In both cases, the number of address pins used should be 6. Also, I have used GPIOs 17-25 for Compact Flash signals.
