» Functional Description
The PIO-D56/D24 consists of one 24-bit port, one 16-bit input port and one 16-bit output port (only for PIO-D56).
The 24-bit port emulate mode 0 of the industry standard 8255 programmable peripheral interface (PPI) chip.
Each PPI offers three 8-bit ports, Port A, Port B and Port C. The Port C is divided into 2 nibble-wide (4-bit) ports.
The 24-bit bi-directional ports are configured as inputs upon power-up or reset.
