The use of the auxiliary window to display a VGA window in a direct-color background can be accomplished
by setting ACR2 = ACR0 = logic 0 and ACR1 = MCR2 bit 7 = logic 1 and is illustrated in Figure 2–10. The
user can also configure the auxiliary window to display direct color in the auxiliary window and VGA
everywhere else by setting ACR0 = logic 1 (not shown). Similarly, the auxiliary window can be configured
to display overlay in the window or outside of the window by setting MCR2 bit 7 = logic 0 (not shown).

The use of PSEL to create multiple VGA windows in a direct-color background can be accomplished by
setting ACR0 = ACR1 = logic 0 and ACR2 = logic 1. PSEL is then switched to logic 1 wherever VGA display
is desired. This is illustrated in Figure 2–11. The user can also configure the port select to switch between
overlay and direct color (MCR2 bit 7 = logic 0 not shown) and also invert the fields (ACR0 = logic 1).

The Viewpoint palette supports color-key-switching modes in which color data from the direct-color and
overlay or VGA ports is compared to a set of user-definable color-key registers. Based on the outcome of
the comparison, either direct color, overlay, or VGA are displayed (see Note 24). High and low color-key
registers are provided for each color and overlay/VGA so that ranges of colors can be compared as opposed
to a single color value. The register bit definitions for the color-key OL/VGA (low, high), color-key red (low,
high), color-key green (low, high), and color-key blue (low, high) range registers are shown in Section
2.16.12. The color-key function is controlled by the color-key control register bits 0–4. This register definition
is shown in Section 2.16.11.
