EMERSON KJ3202X1-BA1涡流传感器及前置器
前面板MVME7100前面板上提供以下开关、LED和连接器。每个复位/中止开关的位置见图3-1。MVME7100有一个按钮开关，可提供中止和复位功能。当开关按下少于3秒时，MC8641D PIC会产生一个中止中断。如果开关保持超过3秒，则会生成板硬复位。如果MVME7100是VMEbus系统控制器，则会生成VME SYSRESET。LED下表描述了MVME71000前面板上的LED。有关LED位置，请参阅第47页图3-1。BFL板故障前面板红色。此指示灯在硬复位期间点亮，并保持点亮，直到软件将其关闭。LED由Tsi148中VSTAT寄存器的第14位（BDFAIL）控制。USR1用户定义前面板红色/黄色此指示灯由状态指示器寄存器中相应寄存器位的S/W断言点亮。有关详细信息，请参阅《程序员指南》。
Front Panel The following switch, LEDs, and connectors are available on the MVME7100 front panel. Refer to Figure 3-1 for the location of each.Reset/Abort Switch The MVME7100 has a single push button switch to provide both the abort and reset functions. When the switch is depressed for less than 3 seconds, an abort interrupt is generated to the MC8641D PIC. If the switch is held for more than 3 seconds, a board hard reset is generated. If the MVME7100 is the VMEbus system controller, a VME SYSRESET is generated.LEDs The next table describes the LEDs on the front panel of the MVME7100. Refer to Figure 3- 1 on page 47 for LED locations.BFL Board Fail Front panel Red This indicator is illuminated during a hard reset and remains illuminated until software turns it off. The LED is controlled by bit 14 (BDFAIL) of the VSTAT register in the Tsi148. USR1 User Defined Front panel Red/Yellow This indicator is illuminated by S/W assertion of its corresponding register bits in the Status Indicator Register. See the Programmer's Guide for further detail.
