飛利浦4522-167-02301除了數(shù)據(jù)之外，還具有通過網(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(jié)點(diǎn)，或者全局地廣播到網(wǎng)絡(luò)上的所有節(jié)點(diǎn)。每個網(wǎng)絡(luò)中斷包包含發(fā)送方的節(jié)點(diǎn)ID、目標(biāo)（目的地）節(jié)點(diǎn)ID、中斷類型信息和32位用戶定義數(shù)據(jù)。Philips 4522-167-02301
網(wǎng)絡(luò)中斷的類型包括四（4）個通用中斷。發(fā)送節(jié)點(diǎn)使用三個RFM控制和狀態(tài)寄存器指定目標(biāo)（目的地）節(jié)點(diǎn)、中斷類型和32位數(shù)據(jù)。每個接收節(jié)點(diǎn)在中斷包通過時對其進(jìn)行評估。
如果中斷指向該節(jié)點(diǎn)，則發(fā)送器的節(jié)點(diǎn)ID存儲在適當(dāng)?shù)陌l(fā)送器ID FIFO（四個之一）中。發(fā)送方ID FIFO深度為127個位置。數(shù)據(jù)將存儲在配套的127個位置的深度數(shù)據(jù)FIFO中。Philips 4522-167-02301
如果通過LISR、LIER和VINT_EN寄存器啟用，四個可能的網(wǎng)絡(luò)中斷中的任何一個也可以在每個接收節(jié)點(diǎn)生成主機(jī)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
