MVME172-523A

如果系统中有其他SCSI大容量存储设备，请确保在SCSI链中的***一个设备上安装了终结器。本地资源MVME187包括许多用于本地处理器的资源。这些包括滴答计时器、软件可编程硬件中断、看门狗计时器和本地总线超时。可编程时钟提供四个分辨率为1µs的32位可编程时钟，其中两个在VMEcchip2中，两个在PCCchip2中。滴答计时器可以被编程为向处理器产生周期性中断。看门狗定时器VMEchip2中提供了看门狗定时器功能。当看门狗计时器启用时，必须在编程时间内由软件复位，否则超时。看门狗定时器可编程为在超时时生成SYSRESET信号、本地复位信号或板故障信号。

产品英文详情料:

If there are additional SCSI mass storage devices in your system, make sure that terminators are installed on the last device in the SCSI chain.Local Resources The MVME187 includes many resources for the local processor. These include tick timers, software programmable hardware interrupts, watchdog timer, and local bus timeout. Programmable Tick Timers Four 32-bit programmable tick timers with 1 µs resolution are provided, two in the VMEchip2 and two in the PCCchip2. The tick timers can be programmed to generate periodic interrupts to the processor. Watchdog Timer A watchdog timer function is provided in the VMEchip2. When the watchdog timer is enabled, it must be reset by software within the programmed time or it times out. The watchdog timer can be programmed to generate a SYSRESET signal, local reset signal, or board fail signal if it times out.
