EP9307 backlight off problem

Note: This was originally posted on 14th July 2011 at http://forums.arm.com

I have a device with touch screen LCD and backlight using ep9307 controller of ARM processor. The problem is that we need to completely switch off the backlight so as to make the screen look dead.

Being a newbie in this field, I have no idea how to do that. After studying the schematics and user guide I came to know Brightness control register named as BRIGHT.But I have no idea how to write to that register.

I need to know how to do that. Can anyone please help.
