DIL/NetPC DNP/1110: PIO Mapping

The bits of the DNP/1110 20-bit PIO (Parallel Input Output Port) are direct connected to signals of the Intel StrongARM SA-1110 microcontroller. The following table shows the mapping. The PIO Port C pins PC0 to PC3 can be used with the SA-1100 Serial Channel 4 / CODEC.
