Backlight Control
Figure 4-8.
The LCD backlight is made of four integrated white chip-LEDs arranged in parallel. These are driven by
an AAT3155 charge pump, MN8.The AAT3155 is controlled by the SAM3S through a single PIO line
PC13 interface; the 0 Ohm resistor R68 is mounted in series on this line, which permits to use it for other
custom purposes. In that case, the pull-up resistor R64 maintains the charge pump permanently enabled
by default.
On the anode drive line, a 0 Ohm resistor R59 is implemented in series for an optional current limitation.
