Hello,

We don't have many GPIOs left and I just want to know whether I can use Data bus
as GPIO. I'm using 6412 TI dsp which has 64 bit width data bus and we are using
only 16 of the data bus, so rest are not used. 

Thanks,

I don't think data bus pins can be used as GPIO -- of course, you could always
define an arbitrary asynchronous space
(CEn) and then use the entire data bus as you wish.

Some McBSP pins can be used as GPIO.  Are you using those?

Also the TOUT0 and TOUT1 pins can be used as general-purpose output (but output
only).
