Figure 2-2 : LPC2214 microcontroller with oscillators connection schematic
The LPC2214 microcontroller is connected to the X1 oscillator. The X1 oscillator generates a clock used for the operation
of the microcontroller. The microcontroller can be cleared by feeding the reset pin with a logic 0, i.e. by pressing the
RESET button.
