Hi,
I have not been able to get the shared GPIO's (above 7) to work. I'm using CSL and CC Studio v.3.3. My system is booting from 24-bit serial flash, and GPIO[0..3] = 0100b at boot-up, so this should make the Parallel Port Mode bit field 11b (in the External Bus Selection reg.). This, in turn, should enable the higher GPIO pins, but when I try to access the pins, nothing happens. The fixed, lower numbered GPIO pins work fine.
Any suggestions?
Thanks,
Bill
