Main Expansion Header

All port pins on LPC2148 microcontroller are accessible on the 50 pin main expansion
header. 50 pin FRC wire can also be connected to this connector. The expansion header
allows user to interface external peripherals to LPC2148 microcontroller. Apart from port
pins, it also includes 3.3V supply which can be utilised to power external devices. When
using the expansion header, it is necessary to disconnect the on-board peripherals
connected to these pins by removing the jumpers which links these pins to the on-board
peripherals. Refer following sections for jumper settings.
