Programming Notes and Examples
Issue Date: 99/04/27
Example 8: Pan the above SwivelView mode image to the right by 4 pixels then
To pan by four pixels the start address needs to be advanced.
To scroll by 4 lines we have to change the start address by the offset of four lines of display.
Set Screen1 Display Start Word Address LSB (REG[0Ch]) to 81h and Screen1 Display
Start Word Address MSB (REG[0Dh]) to 02h.
1. Calculate the amount to change start address by.
2. Increment the start address registers by the just calculated value.
1. Calculate the amount to change start address by.
2. Increment the start address registers by the just calculated value
Bytes = Pixels x BitsPerPixel / 8 = 4 x 4 / 8 = 2 bytes
In this case the value writen to the start address register will be 81h (7Fh + 2 = 81h)
BytesPerLine = LineByteCount = 128
Bytes = Lines x BytesPerLine = 4 x 128 = 512 = 200h
In this case 281h (81h + 200h) will be written to the Screen 1 Start Word Address reg-
ister pair.
scroll it up by 6 pixels.
