8 / 19 page MYSON TECHNOLOGY MTV048 (Rev 0.9) Rev 0.9 - 8 - 2001/03/15 column characters could be displayed on screen and the odd column characters will be hidden. ATTRIBUTE Bytes: Attribute registers, (ROW 0 ~ 14, COLUMN 0 ~ 29), B7 B6 B5 B4 B3 B2 B1 B0 - BGR/BOX2 BGG/BOX1 BGB/BOX0 BLINK R G B BGR, BGG, BGB : These three bits define the background color for their individual relative address characters. If these three bits are set to (0, 0, 0), no background will be shown (transparent). Therefore, a total of 7 background colors can be selected. BOX2-0 - Select the character button boxes format of its relative address character. = 0, 0, 0 ⇒ Button boxes is disabled. = 1, 0, 0 ⇒ Start of depressed button box which is more than 1 character button box. = 1, 0, 1 ⇒ Start of depressed button box which is only 1 character button box. = 1, 1, 0 ⇒ Start of raised button box which is more than 1 character button box. = 1, 1, 1 ⇒ Start of raised button box which is only 1 character button box. = 0, 1, 0 ⇒ Middle of button box. = 0, 0, 1 ⇒ End of button box. BLINK = 1 ⇒ Enable blink effect for its relative address character. And the blinking is alternate per 32 vertical frames. = 0 ⇒ Disable blink effect for its relative address character. R, G, B - These three bits are used to specify their individual relative address character foreground color. 3.7 Character Button Boxes Generator There are 4 character button box generators to generate 4 different types of button boxes including depressed button box with only 1 character, depressed button box with more than 1 character, raised button box with only 1 character, and raised button box with more than 1 character. The button boxes format is defined by (BOX2, BOX1, BOX0) bits of attribute bytes. And these bits are described as below: 1). (1, x, x) means the start of character button box, and than BOX1-0 bits define the format of button box. 2). (0, 1, 0) means the middle of character button box. 3). (0, 0, 1) means the end of character button box. The length of button box is also software control by (BOX2, BOX1, BOX0) bits. For example, if there is 1 raised button box whose length is equal to 6 characters, these BOX2-0 bits will be (1, 1, 0), (0, 1, 0), (0, 1, 0), (0, 1, 0), (0, 1, 0), (0, 0, 1). And if there is 1 depressed button box whose length is equal to 4 characters, these BOX2-0 bits will be (1, 0, 0), (0, 1, 0), (0, 1, 0), (0, 0, 1). That is, (0, 1, 0) command's number defines the button box length. And only 1 byte, the attribute byte of button box start character, should be modified when changing button box type from raised button to depressed button, or vice versa. This is very easy and useful for software programming. 3.8 Character ROM MTV048 character ROM contains 384 characters and symbols including 360 standard fonts, 8 user fonts and 16 multi-color fonts. The 360 standard fonts are located from address 0 to 359. The 8 user fonts are located from address 360 to 367.And the 16 multi-color fonts are located from address 368 to 383. Each character and symbol consists of 12x18 dots matrix. |
