this macro in parallel with accesses to the device.
Mode must
be one of the expressions listed below.
The VGA modes drive the VGA connector with VESA GTF
compatible timings. The horizontal resolution will adapt
according to
ClockRate. To achieve standard resolutions, set
the clock frequency to the appropriate value for the
resolution, as shown in the table below.
To use the LCD panel, the clock frequency must be exactly
25.175 MHz. When using the LCD the VGA connector is also
driven, providing a dual display capability (although the
image will be the same on both displays).
