飛利浦4522-167-02301除了數據之外，還具有通過(guò)網(wǎng)絡(luò )傳遞中斷分組的能力。網(wǎng)絡(luò )中斷分組可以被定向到特定節點(diǎn)，或者全局地廣播到網(wǎng)絡(luò )上的所有節點(diǎn)。每個(gè)網(wǎng)絡(luò )中斷包包含發(fā)送方的節點(diǎn)ID、目標（目的地）節點(diǎn)ID、中斷類(lèi)型信息和32位用戶(hù)定義數據。Philips 4522-167-02301

網(wǎng)絡(luò )中斷的類(lèi)型包括四（4）個(gè)通用中斷。發(fā)送節點(diǎn)使用三個(gè)RFM控制和狀態(tài)寄存器指定目標（目的地）節點(diǎn)、中斷類(lèi)型和32位數據。每個(gè)接收節點(diǎn)在中斷包通過(guò)時(shí)對其進(jìn)行評估。

如果中斷指向該節點(diǎn)，則發(fā)送器的節點(diǎn)ID存儲在適當的發(fā)送器ID FIFO（四個(gè)之一）中。發(fā)送方ID FIFO深度為127個(gè)位置。數據將存儲在配套的127個(gè)位置的深度數據FIFO中。Philips 4522-167-02301

如果通過(guò)LISR、LIER和VINT_EN寄存器啟用，四個(gè)可能的網(wǎng)絡(luò )中斷中的任何一個(gè)也可以在每個(gè)接收節點(diǎn)生成主機VMEbus中斷。Philips 4522-167-02301

英文資料：

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
