I'm using one of the older TMS470 parts (TMS470R1B1M). I have configured the SPI1 and SPI2 lines as GIO and am using them as inputs. When the pins are not connected to anything, they appear to be floating. Is the no internal pullup or pulldown on the SPI pins when they are configured as GIO? The datasheets seems to imply so, but I am just looking for some confirmation.
