Description
Reserved.
Compressed Display Buffer Start Offset. This value represents the byte offset of the
starting location of the compressed display buffer. The lower five bits should always be
programmed to zero so that the start offset is aligned to a 32-byte boundary. This value
should change only when a new display mode is set due to a change in size of the frame
buffer.
Description
Reserved.
Cursor Start Offset. This value represents the byte offset of the starting location of the
cursor display pattern. The lower five bits should always be programmed to zero so that
the start offset is 32-byte aligned. Note that if there is a Y offset for the cursor pattern, the
cursor start offset should be set to point to the first displayed line of the cursor pattern.
