DIL/NetPC DNP/9200: PIO Mapping
The DNP/9200 PIO bits PA0 to PA7, PB0 to PB7 and PC0 to PC3 are driven by the Atmel AT91RM9200 ARM9-based 32-bit microcontroller internal parallel input/output
controller. This controller manages up 32 fully programmable input/output lines. 20 of these lines are used to implement the DNP/9200 20-bit PIO (Parallel Input
Output Port). The bits of the DNP/9200 20-bit PIO are direct connected to signals of the Atmel AT91RM9200. The following table shows the mapping.

Please Note: Each AT92RM9200 parallel I/O pin is configurable, according to product definition as either a general-purpose I/O line
only, or as an I/O line multiplexed with one or two peripheral I/Os. See also the DNP/9200 alternate function description.
