DISP
O
Display enable
Display enable signal output to the LCD. This output is used as the blanking
signal in external RAMDAC mode and as the display enable signal when a TFT
LCD panel is used.
SCK
O
Shift clock
Data shift clock output to an STN LCD panel. This output is used as the dot clock
output for a TFT LCD panel or in external RAMDAC mode.
UD[7 : 0]
O
Upper/Lower data 7 : 0
LD[7 : 0]
Display data outputs.
In external RAMDAC mode LD[7:0] are used as the display data and UD[0:7] are
used as the write data lines to the RAMDAC register.
The table below shows the pin functions for each panel type.
