6062M–ATARM–23-Mar-09
The LCDVSYNC is asserted once per frame. This signal is asserted to cause the LCD's line
pointer to start over at the top of the display. The timing of this signal depends on the type of
LCD: STN or TFT LCD.
In STN mode, the high phase corresponds to the complete first line of the frame. In STN mode,
this signal is synchronized with the first active LCDDOTCK rising edge in a line.
In TFT mode, the high phase of this signal starts at the beginning of the first line. The following
timing parameters can be selected:
There are two other parameters to configure in this module, the HOZVAL and the LINEVAL
fields of the LCDFRMCFG:
