25.2.14 LCDC Vertical Sync Signal Register (LDVSYNR)
LDVSYNR specifies the timing of the generation of the vertical (scan direction and vertical
direction) sync signals (FLM/Vsync) for the LCD module.
Bit 11—Reserved
Bits 15 to 12—Vertical Sync Signal Width (VSYNW): Set the width of the vertical sync signals
(FLM and Vsync) (unit: line).
Subtract 2 from the setting (0 to 15 (H'F)).
Example: For a vertical sync signal width of 1 line
Bits 10 to 0— Vertical Sync Signal Output Position (VSYNP): Set the output position of the
vertical sync signals (FLM and Vsync) (unit: line).
Subtract 2 from the setting (0 to 2046 (H'7FE)).
DSTN should be set to an odd number value. It is handled as (setting value + 1)/ 2.
Example: For an 480-line LCD module and a vertical retrace period of 0 lines (in other words,
