I am trying to understand how the parallel LCD display interface is used, from the Sabre Lite schematic.
That board was presumably designed with a particular (class of) display in mind: can someone tell me what it is? Then I'll get it's documentaion, & understand more.
Particularly, I need to understand better what these signals are used for:
PWM1 (pin 37) - what does this do?
DRDY (pin 34) - is this Data Enable?
CNTRST (pin 4) - this sounds like "contrast": is it a PWM signal?
Regards & thanks,
