飞利浦4522-167-02301除了数据之外，还具有通过网络传递中断分组的能力。网络中断分组可以被定向到特定节点，或者全局地广播到网络上的所有节点。每个网络中断包包含发送方的节点ID、目标（目的地）节点ID、中断类型信息和32位用户定义数据。Philips 4522-167-02301

网络中断的类型包括四（4）个通用中断。发送节点使用三个RFM控制和状态寄存器指定目标（目的地）节点、中断类型和32位数据。每个接收节点在中断包通过时对其进行评估。

如果中断指向该节点，则发送器的节点ID存储在适当的发送器ID FIFO（四个之一）中。发送方ID FIFO深度为127个位置。数据将存储在配套的127个位置的深度数据FIFO中。Philips 4522-167-02301

如果通过LISR、LIER和VINT_EN寄存器启用，四个可能的网络中断中的任何一个也可以在每个接收节点生成主机VMEbus中断。Philips 4522-167-02301

The Philips 4522-167-02301 has the capability of passing interrupt packets over the network in addition to data. The network interrupt packets can be directed to a specific node or broadcast globally to all nodes on the network. Each network interrupt packet contains the sender’s node ID, the target (destination) node ID, the interrupt type information and 32 bits of user defined data.Philips 4522-167-02301

The types of network interrupts include four (4) general purpose interrupts. The sending node specifies the target (destination) node, the interrupt type and 32 bits of data using three RFM Control and Status registers. Each receiving node evaluates the interrupt packets as they pass through.

 If the interrupt is directed to that node, then the sender’s node ID is stored in the appropriate Sender ID FIFO (one of four). The Sender ID FIFO is 127 locations deep. The data will be stored in a companion 127 locations deep data FIFO.Philips 4522-167-02301

If enabled through the LISR, LIER and VINT_EN registers, any of the four possible network interrupts can also generate a host VMEbus interrupt at each receiving node.Philips 4522-167-02301
