Buffered: Buffermode=mcBuffered. See two cases as below.
1. When the direction of the buffered
instruction is the same as that of the
current instruction

Blending with low velocity: Buffermode=mcBlendingLow. See three cases as below.
1. When the velocity of the current
instruction is less than that of the
buffered instruction.
