T35 Display setttings

SCA
Hello,

I have a Micro2440 and SDK with T35 Display.

I'm trying to understand the display settings in order to be able to
interface a different LCD.

Reading the S3C2440 manual, the TD035STED4 datasheet, and the WinCE5 source
code provided on the CD seems to show up some inconsistencies.

The code  suggests values for the Horizontal timing that the HBFP
(horizontal front porch, maps to LCD_LEFT_MARGIN), and HSPW (sync pulse
width, LCD_HSYNC_LEN) are less than the Toppoly Datasheet minimum values. 

Measurements with a 'scope suggest that the signals behave as the code
suggests they should. Also, the measured clock frequency is twice the
maximum (75ns period, against 146ns minimum in the datasheet)

The display is working fine, so no worries there, but I'm curious whether
the display datasheet is out of date, or that the parameters really are
that flexible.

Can anyone shed any light on this?

Thanks

Simon
