CRADDR
Bit 7 CCS0 — This bit defines a specific character color
out of the two preset colors. Color 1 is selected if this bit is
cleared, and Color 2 otherwise.
Bit 6–0 CRADDR — These seven bits address the 128
characters or symbols residing in the character ROM.
Bits 2–0 R, G and B — These bits control the color of Win-
dow 1. Window 1 occupies Columns 0–2 of Row 15; Window
2 occupies Columns 3–5; and Window 3 occupies Columns
6–8. Window 1 has the highest priority, and Window 3 the
least. If window overlapping occurs, the higher priority win-
dow will cover the lower one, and the higher priority color will
take over on the overlap window area. If the start address is
greater than the end address, this window will not be dis-
played.
