The BitBLT FIFO Not Empty Status bit is a read-only status bit. When this bit returns a 0,
the BitBLT FIFO is empty. When this bit returns a 1, the BitBLT FIFO contains at least one
data.

The BitBLT FIFO Half Full Status bit is a read-only status bit. When this bit returns a 0,
the BitBLT FIFO is less than half full (contains 7 or less data). When this bit returns a 1,
the BitBLT FIFO is half full or greater than half full (contains 8 or more data).

The BitBLT Destination Linear Select bit specifies the storage method of the destination
blit. If this bit = 0, the destination blit is stored as a rectangular region of memory. If this
bit = 1, the destination blit is stored as a contiguous linear block of memory.
