respective control signals to be used on the expansion II interface. See
Table 2-10.
DPI [9–14] Enable Switch (SW14)
The DPI [9–14] enable switch (SW14) disconnects DPI pins nine through
14 on the processors from the associated peripherals on the EZ-Board and
allows the DPI signals to be used on the expansion II interface. See
Table 2-11.
