Detailed Description

Bitblit operations on misaligned words.

Bitblt Operations

The following restrictions apply:

• The destination buffer must be word-aligned.
• The source buffer must be misaligned if the bit offset is 0.
• Both row dimensions must be word-aligned.
• The bit offset must be in the range 0 - 7.
