CCS/TMS320C6748: TMS320C6748 LCDC controller - always an hsync before vsync

Part Number: TMS320C6748

Tool/software: Code Composer Studio

Hi everyone,

The LCDC peripheral on the 6748 always seems to put out a single line sync before a frame sync, which is causing problems with our display. Does anyone know how to correct or work around this? Our display seems to require a Vsync at the start of the frame before any Hsync's or it loses a row of data.

We'd prefer to use non-inverted sync pulses, but I have played around with inverting them, as well as other Raster Timing register settings with limited success.
