The S3C2410A has 117 multi-functional input/output port pins. The ports are:

— Port A (GPA): 23-output port

— Port B (GPB): 11-input/output port

Each port can be easily configured by software to meet various system configurations and design requirements. You
have to define which function of each pin is used before starting the main program. If a pin is not used for multiplexed
functions, the pin can be configured as I/O ports.

Initial pin states are configured seamlessly to avoid problems.
