邊界掃描頭（P5）20針邊界掃描頭為板載PLD編程和邊界掃描測(cè)試/調(diào)試提供接口。此標(biāo)頭的引腳分配如下：概述MVME7100 VMEbus板基于MC8640D（1.067GHz版本）和MC8641D（1.33GHz版本）集成處理器。MVME7100提供前面板訪問一個(gè)帶有迷你DB-9連接器的串行端口、兩個(gè)帶有兩個(gè)RJ-45連接器的10/100/1000以太網(wǎng)端口以及一個(gè)帶有一個(gè)a類連接器的USB端口。前面板包括故障指示燈LED、用戶定義的指示燈LED和復(fù)位/中止開關(guān)。MVME7216E轉(zhuǎn)換模塊提供對(duì)四個(gè)串行端口（每個(gè)端口一個(gè)RJ-45連接器）和兩個(gè)10/100/1000以太網(wǎng)端口（兩個(gè)RJ-45接口）的后面板訪問。轉(zhuǎn)換模塊還為一個(gè)帶前端I/O的PIM提供兩個(gè)平面連接器。MVME7100單板計(jì)算機(jī)的框圖如圖4-1所示，MVME7216E轉(zhuǎn)換模塊的框圖如
Boundary Scan Header (P5) The 20-pin boundary scan header provides an interface for programming the on-board PLDs and for boundary scan testing/debug purposes. The pin assignments for this header are as follows:Overview The MVME7100 VMEbus board is based on the MC8640D (1.067GHz versions) and the MC8641D (1.33GHz versions) integrated processors. The MVME7100 provides front panel access to one serial port with a mini DB-9 connector, two 10/100/1000 Ethernet ports with two RJ-45 connectors, and one USB port with one type A connector. The front panel includes a fail indicator LED, user-defined indicator LED, and a reset/abort switch. The MVME7216E transition module provides rear panel access to four serial ports with one RJ-45 connector per port and two 10/100/1000 Ethernet ports with two RJ-45 connectors. The transition module also provides two planar connectors for one PIM with front I/O. The block diagram for the MVME7100 Single Board Computer is shown in Figure 4-1 and the block diagram for the MVME7216E transition module
