由NMI批准。SERR中断通过特定逻辑路由回CPU上的NMI输入线。CPU读取NMI状态控制寄存器以确定NMI源(位设置为1)。NMI中断例程处理中断后,软件通过将相应的启用/禁用位设置为1来清除NMI状态位。NMI启用和实时时钟寄存器可以屏蔽NMI信号并禁用/启用所有NMI源。表3-5 NMI寄存器位描述状态控制寄存器(I/O地址$061,读/写,只读)位7 SERR#NMI源状态(只读)-如果系统板代理检测到系统板错误,该位设置为1。然后,它断言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,位7必须为0。位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)位7 NMI启用-1=禁用,0=启用49个I/O端口3个I/O端口VMIVME-7740包含SMC Super-I/O芯片。SMC芯片为VMIVME-7740提供了一个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。使用默认中断,所有端口都位于其标准PC/AT位置。图3-1 PC中断逻辑控制器BERR*ACFAIL*IRQ1*IRQ2*IRQ3*I的连接ed by the NMI. The SERR interrupt is routed through certain logic back to the NMI input line on the CPU. The CPU reads the NMI Status Control register to determine the NMI source (bits set to 1). After the NMI interrupt routine processes the interrupt, software clears the NMI status bits by setting the corresponding enable/disable bit to 1. The NMI Enable and Real-Time Clock register can mask the NMI signal and disable/enable all NMI sources. Table 3-5 NMI Register Bit Descriptions Status Control Register (I/O Address $061, Read/Write, Read Only) Bit 7 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 49 I/O Ports 3 I/O Ports 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.
