Writing 1s produces lows at the corresponding port pins. Download the complete project folder from this link. Every GPIO pin has a minimum of interfaing function and max of four functions.

Port Output Set Register.

C program of led interfacing with ARM7 ( LPC )

By l;c2148, the first 16 P0. Program to demonstrate the LED blinking. It is recommended to configure the PORT direction and pin function before using it.

As there can be up to 4 functions associated with a GPIO pin, two bits for each pin are available to select the function. Every GPIO pin has a minimum of one function and max of four functions.

This register individually controls the direction of each port pin. The current state of digital port pins can be read from this register, regardless of pin direction or alternate function selection as long as pins are not configured as an input to ADC.

It is recommended to configure the PORT direction and pin function before using it. Writing 1s produces lows at the corresponding port pins. Writing to this register places corresponding values in all bits of the particular PORT pins.
