Dolphin GPIO Controller
Dolphin Technology provides General Purpose I/O IP which cosists of up to 32 I/O ports that can be programmed individually for input, output, or bidirectional operation. Each port can be programmed to trigger the GPIO interrupt on level (high, low) or edge (rising, falling, any) events. The IP serves as additional means of communication between various components of the system on chip (SoC).
