ABB 70AA01A-E HESG446212R1输出模拟
SERR#NMI源状态（只读）-如果系统板代理检测到系统板错误，则此位设置为1。然后断言PCI SERR#线。要重置中断，请将位2设置为0，然后将其设置为1。写入端口$061时，第7位必须为0。Bit 2 PCI SERR#启用（读/写）-1=清除和禁用，0=启用启用和实时时钟地址寄存器（I/O地址$070，仅写）Bit 7 NMI启用-1=禁用，0＝启用VMIVME-7740包含SMC Super I/O芯片。SMC芯片为VMIVME-7740提供了标准软盘驱动器控制器和两个16550 UART兼容串行端口。Ultra IDE硬盘驱动器接口由Intel 82371EB（PIIX4E）PCI ISA IDE Xcelerator芯片提供。所有端口都使用默认中断出现在其标准PC/AT位置。视频图形适配器VMIVME-7740上的监视器端口由芯片和技术69030视频适配器芯片控制，该芯片具有4 Mbyte嵌入式视频SDRAM。
SERR# NMI Source Status (Read Only) - This bit is set to 1 if a system board agent detects a system board error. It then asserts the PCI SERR# line. To reset the interrupt, set bit 2 to 0 and then set it to 1. When writing to port $061, bit 7 must be 0. Bit 2 PCI SERR# Enable (Read/Write) - 1 = Clear and Disable, 0 = Enable Enable and Real-Time Clock Address Register (I/O Address $070, Write Only) Bit 7 NMI Enable - 1 = Disable, 0 = Enable The VMIVME-7740 incorporates the SMC Super-I/O chip. The SMC chip provides the VMIVME-7740 with a standard floppy drive controller and two 16550 UART-compatible serial ports. The Ultra-IDE hard drive interface is provided by the Intel 82371EB (PIIX4E) PCI ISA IDE Xcelerator chip. All ports are present in their standard PC/AT locations using default interrupts.Video Graphics Adapter The monitor port on the VMIVME-7740 is controlled by a Chips and Technology 69030 video adapter chip with 4 Mbyte embedded video SDRAM.
