2.16.16 Blank Function
The blank function can output blank (OUT1) area on all sides (vertical and horizontal) of the screen. This
provides the blank signal, wipe function, etc., when outputting a 3 : 4 image on a wide screen.
The ON/OFF for vertical blank function is performed by bit 5 of the OSD control register 1 and is used to
select vertical window function or vertical blank function by bit 6 of the OSD control register 2. Accord-
ingly, the vertical blank function cannot be used simultaneously with the vertical window function. The top
border is set by the top border control register (TBR), and the bottom border is set by the bottom border
control register (BBR), in 1H units.
The ON/OFF for horizontal blank function is performed by bit 4 of the OSD control register 2 and is used
interchangeably for the horizontal window function with bit 5 of the OSD control register 2 . Accordingly,
the horizontal blank function cannot be used simultaneously with the horizontal window function. The left
border is set by the left border control register (LBR) and the right border is set by the right border control
register (RBR), in 4T
The OSD output (except raster) in area with blank output is not deleted.
These blank signals are not output in the horizontal/vertical blanking interval.
Notes 1. Horizontal blank and horizontal window, as well as vertical blank and vertical window can not be
