Eurotech Appliances PXA270 LVDS_FES#, (EXP2_GPIO1), Selected LVDS function

ZEUS Technical Manual	Detailed hardware description

The LVDS transmitter can be programmed for rising edge strobe or falling edge strobe operation through a signal LVDS_FES# (Expander 2 – GPIO1, I2C address 0x22). Details are shown in the following table:

LVDS_FES#
(EXP2_GPIO1)	Selected LVDS function
0	Falling edge strobe
1	Rising edge strobe (default)

Connector J24 should be used to supply the power and brightness control for the backlight inverter when the LVDS interface is used. See the section J24 – Backlight power, page 92, for details.
