also from 9054 datasheet

When the PCI 9054 acknowledges BREQi assertion during DMA or PCI Target Write transfers, it releases the Local Bus within two Lword transfers by de-asserting LHOLD and floating the Local Bus outputs if either of the following
conditions exist:
• BREQi is asserted and enabled
• Gating is enabled and the Local Bus Latency Timer
  is enabled and expires (MARBR[27, 7:0])

1。我怎么觉得这话不通呀，从字面的意思是，如果Local Bus Latency Timer流逝了，9054还不能放弃局部总线，还要等BERQi有效才行。是这样的码？

2。Gating 是什么？

floating  是浮空之意.而非流逝之意.
Gating 是控制门之意

there is no point on \"floating\", what i wonder is the logic of the sentence i presented.but anyway thanks ur \"Gating\" gift.
