看門狗定時器邏輯在RELIANCE 803456-37RC。由于VMEchip2中的看門狗計時器功能是MC2芯片中該功能的超集（系統重置功能），因此除了不包含VMEbus接口的控制器版本（“無VMEbus界面”選項）外，VMEchif2中的計時器在所有情況下都使用。軟件可編程硬件中斷VMEchip2提供八個軟件可編程的硬件中斷。這些中斷允許軟件創建硬件中斷。本地總線超時MVME162FX嵌入式控制器在VMEchip2和MC2芯片中為本地總線提供超時功能。當定時器被啟用并且本地總線訪問超時時，RELIANCE 803456-37RC傳輸錯誤確認（TEA）信號被發送到本地總線主控器。軟件可選擇8μsec、64μsec、256μsec或無限長的超時值。本地總線計時器在VMEbus綁定周期內不工作。VMEbus綁定周期由VMEbus訪問計時器和VMEbus全局計時器計時。在VMEchip2和MC2芯片ASIC中復制訪問定時器邏輯。由于VMEchip2中的本地總線計時器可以檢測到非板外訪問，而MC2芯片本地總線計時器無法檢測到，因此除了不包含VMEbus接口的控制器版本（“No VMEbus interface option”）外，VMEcchip2中的計時器在所有情況下都使用。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
