which is caused when signal changes do not align with the color clock and so do not provide the TV/monitor hardware adequate time to reach the correct color.) Character Modes Glyph Rendering All character sets use 8 sequential bytes to represent the character. Four types of character/glyph rendering of those bytes are available. Each Character Mode is associated to a specific rendering method: Standard: ANTIC Mode 2. Based on the high resolution graphics modes each bit in the character glyph represents one pixel on screen that is 1/2 color clock wide. The background color is rather than COLBK used in other Character and Map modes. COLBK appears as a border around all four sides of the Playfield. 0 value bits in the character glyph show the background color. 1 value bits show the luminance value from based on the background (COLPF2) color. The character set uses 128 characters and requires 1024 bytes of RAM. Descenders: ANTIC Mode 3. A modification of the Standard method. The method of pixel color display is the same. Each mode line is 10 scanlines tall, though the character glyph is still 8 bytes. Characters hex/0dec to hex/95dec display in the top 8 scan lines with two blank scan lines added at the bottom. Characters hex/96dec to hex/127dec begin with two blank scan lines at the top, and then display the glyph bytes in the bottom 8 scan lines. The first two bytes in the glyph are moved to the bottom two scan lines. This allows a properly designed character set to display true descenders. The character set uses 128 characters and requires 1024 bytes of RAM. Single Color: ANTIC Modes 6 and 7. In these modes each bit in the character glyph represents one pixel that is one color clock wide. The background color is COLBK. Characters may be displayed in a choice of one of four colors. The six low bits of the character value identifies the glyph and the two high bits identify a color. Since the character value is reduced to six bits the character set uses 64 characters and requires 512 bytes of RAM. 0 value bits in the character glyph show the background color. 1 value bits in the glyph data shows one of four possible color choices based on the two high bits of the character value. Character value bits 7 and 6: Multi-Color: ANTIC Modes 4 and 5.
