Programming Notes and Examples
Issue Date: 2002/08/21
Note
When the end of a row is reached and destination linear is selected the destination address
is updated to the next available memory offset. The result is data which is jammed
together with one row immediately following the next in display memory. This is useful
when it is desired to compactly save a rectangular area into off screen memory.
When this bit = 0, the BitBLT destination is stored as a rectangular region of memory.
When this bit = 1, the BitBLT destination is stored as a contiguous linear block of mem-
ory.
The Source Linear Select bit determines how the source address pointer is updated when
the BitBLT reaches the end of a row.
When the end of a row is reached and rectangular is selected the source address is updated
to point to the beginning of the next row of a rectangular area. The offset to the start of the
next row is contained in the BitBLT Memory Address Offset register (REG[8014h]).
When the end of a row is reached and source linear is selected the source address is
updated to the next available memory offset. The result is data, which was jammed
together with one row immediately following the next in display memory, can now be
expanded back to a rectangular area.
When this bit = 0, the BitBLT source is stored as a rectangular region of memory.
When this bit = 1, the BitBLT source is stored as a contiguous linear block of memory.
This bit is write only.
Setting this bit to 1 begins the 2D BitBLT operation. This bit must not be set to 0 while a
BitBLT operation is in progress.
To determine the status of a BitBLT operation use the BitBLT Busy Status bit
(REG[8004h] bit 0).
