System connector (P1102)
A 2x12-pin connector is used for the connection of signals that are typical of the system. Power button, reset,
speaker, LEDs for hard disk and for Suspend mode are connected here along with three further status LEDs
that are controlled via GPIOs. Of these three LEDs, LED1 and LED2 are already equipped with series
resistors. The pin assignment is designed so that associated pins are located opposite or near to each other.
