A parallel interface is provided on ball-out. This interface include 16 bits data lines (DPROC<0..15>), 3
address lines (APROC<1>, APROC<2>, APROC<3>), Write control signal RWPROC* (active low), Read
control signal OEPROC* (active low) and one chip select CS1PROC* (active low). This interface is dedicated
to external companion chip interface (as external DSP for additional multimedia applications).
This interface supports page mode.
