请高手指教 PCI 9054的USERo/DREQO#/LLOCKo#怎么连？

我在用9054
USERi/DACK0#/LLOCKi#和USERo/DREQO#/LLOCKo#这两个脚怎么连啊？
还有TEST是接地吗？

下面是手册中的说明，我看不明白。。
1.TEST脚：Pulled high for test and low for normal operation.When pulled high:
    All outputs except USERo/DREQ0#/LLOCKo# and LEDon/LEDin are placed in tri-    state. USERo/DREQ0#/LLOCKo# provides NANDTREE output.
2. USERi/DACK0#/LLOCKi#: Multiplexed input/output pin.
    (User Input)USERi:
    General-purpose input that can be read by way of the PCI 9054Configuration
    registers.
    (Demand Mode DMA Acknowledge) DACK0#:
    When a channel is programmed through the Configuration registers to oper
    -ate in Demand mode, this output indicates a DMA transfer is being   
    executed. DACK0# corresponds to PCI 9054 DMA Ch 0.
    (Local Lock Input) LLOCKi#:
    Indicates an atomic operation that may require multiple transactions to complete. Used by the PCI 9054 for direct Local access to the PCI Bus.
3.USERo/DREQO#/LLOCKo#  : Multiplexed input/output pin.
  USERo/ User Output USERo:
General-purpose output controlled from the PCI 9054 Configuration registers.
  DREQ0#/ Demand DMA Request DREQ0#:
When a channel is programmed through the Configuration registers to operate in Demand mode, this input serves as a DMA request. DREQ0# corresponds to PCI 9054 DMA Ch 0.
LLOCKo# Local Lock Output LLOCKo#:
Indicates an atomic operation for a PCI Target PCI-to-Local Bus access may require multiple transactions to complete.
