Note: Two data parallel mode is selected when DCON '2-d' bridge is open. On default setting the
bridge is set and 4 bits wide data is input to D0...D3 and does NOT require D4...D7 to be
connected.

Description
Signal return
Primary video data. In two data parallel mode
even video data
(see note below and "Two-Data-Parallel" on
page 9).
Odd video data used in two data parallel mode
(see note below and "Two-Data-Parallel" on
page 9).
Synchronizing signal for data lines, HS, VS and
_BLANK. Data inputs are read at the rising
edge of VCLK.
Used in VGA modes. In NORMAL mode should
be high or left disconnected.
The horizontal sync signal HS controls the
internal row counter and in the NORMAL mode
the horizontal position of the picture.
The vertical sync signal VS controls the vertical
position of the picture.
If high or left disconnected, self test is
performed (see page 8).
If high, data bits are interpreted as colours (see
page 8). If low, data bits are interpreted as
binary data. If left disconnected, interpretation
depends on MAP jumper.
Display operation is enabled when high or left
disconnected
If low, display brightness and contrast is
reduced for lower power consumption.
