看門(mén)狗定時(shí)器邏輯在RELIANCE 803456-37RC。由于VMEchip2中的看門(mén)狗計時(shí)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(wú)VMEbus界面”選項）外，VMEchif2中的計時(shí)器在所有情況下都使用。軟件可編程硬件中斷VMEchip2提供八個(gè)軟件可編程的硬件中斷。這些中斷允許軟件創(chuàng )建硬件中斷。本地總線(xiàn)超時(shí)MVME162FX嵌入式控制器在VMEchip2和MC2芯片中為本地總線(xiàn)提供超時(shí)功能。當定時(shí)器被啟用并且本地總線(xiàn)訪(fǎng)問(wèn)超時(shí)時(shí)，RELIANCE 803456-37RC傳輸錯誤確認（TEA）信號被發(fā)送到本地總線(xiàn)主控器。軟件可選擇8μsec、64μsec、256μsec或無(wú)限長(cháng)的超時(shí)值。本地總線(xiàn)計時(shí)器在VMEbus綁定周期內不工作。VMEbus綁定周期由VMEbus訪(fǎng)問(wèn)計時(shí)器和VMEbus全局計時(shí)器計時(shí)。在VMEchip2和MC2芯片ASIC中復制訪(fǎng)問(wèn)定時(shí)器邏輯。由于VMEchip2中的本地總線(xiàn)計時(shí)器可以檢測到非板外訪(fǎng)問(wèn)，而MC2芯片本地總線(xiàn)計時(shí)器無(wú)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(shí)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
