2.产 品 详 情 资 料：
看门狗定时器逻辑在RELIANCE 803456-37RC。由于VMEchip2中的看门狗计时器功能是MC2芯片中该功能的超集（系统重置功能），因此除了不包含VMEbus接口的控制器版本（“无VMEbus界面”选项）外，VMEchif2中的计时器在所有情况下都使用。软件可编程硬件中断VMEchip2提供八个软件可编程的硬件中断。这些中断允许软件创建硬件中断。本地总线超时MVME162FX嵌入式控制器在VMEchip2和MC2芯片中为本地总线提供超时功能。当定时器被启用并且本地总线访问超时时，RELIANCE 803456-37RC传输错误确认（TEA）信号被发送到本地总线主控器。软件可选择8µsec、64µsec、256µsec或无限长的超时值。本地总线计时器在VMEbus绑定周期内不工作。VMEbus绑定周期由VMEbus访问计时器和VMEbus全局计时器计时。在VMEchip2和MC2芯片ASIC中复制访问定时器逻辑。由于VMEchip2中的本地总线计时器可以检测到非板外访问，而MC2芯片本地总线计时器无法检测到，因此除了不包含VMEbus接口的控制器版本（“No VMEbus interface option”）外，VMEcchip2中的计时器在所有情况下都使用。RELIANCE 803456-37RC
The watchdog timer logic is duplicated in theRELIANCE 803456-37RC Because the watchdog timer function in the VMEchip2 is a superset of that function in the MC2 chip (system reset function), the timer in the VMEchip2 is used in all cases except for the version of the controller which does not include the VMEbus interface ("No VMEbus Interface" option). Software-Programmable Hardware Interrupts Eight software-programmable hardware interrupts are provided by the VMEchip2. These interrupts allow the software to create a hardware interrupt.Local Bus Timeout The MVME162FX Embedded Controller provides a timeout RELIANCE 803456-37RCfunction in the VMEchip2 and the MC2 chip for the local bus. When the timer is enabled and a local bus access times out, a Transfer Error Acknowledge (TEA) signal is sent to the local bus master. The timeout value is selectable by software for 8 µsec, 64 µsec, 256 µsec, or infinity. The local bus timer does not operate during VMEbus bound cycles. VMEbus bound cycles are timed by the VMEbus access timer and the VMEbus global timer. The access timer logic is duplicated in the VMEchip2 and MC2 chip ASICs. Because the local bus timer in the VMEchip2 can detect an offboard access and the MC2 chip local bus timer cannot, the timer in the VMEchip2 is used in all cases except for the version of the controller which does not include the VMEbus interface ("No-VMEbus-Interface option").RELIANCE 803456-37RC
