LAS1BA重新映射寄存器,然后访问新窗口。这确保了新的窗口映射已经生效,并且后续的内存访问将指向新的内存窗口。总之,寄存器LAS1RR是与PCI窗口大小相对应的范围寄存器,是只读的。寄存器LAS1BA是可写基址寄存器。它用于重新映射或偏移PCI PIO窗口以访问已安装内存的其他部分。RFM‐5565固件防止用户输入无效的重新映射值。写入的值必须是PCI窗口大小的倍数。例如,使用2 MB的PCI窗口大小和64 MB的安装内存意味着有32个有效的基址设置,从$00000000到$03E00000,递增$00200000(写入时所有其他位都被屏蔽)。此外,具有64 MB窗口的64 MB板卡没有除默认值0之外的有效基址设置。由于PCI窗口大小和重映射寄存器仅影响PCI PIO访问,因此无论重映射值如何,DMA(本地到PCI和PCI本地)通常都可以用于与PCI总线上的另一个位置传输高达$7FFFFF字节。编程64 3.7网络中断处理示例以下是设置RFM‐5565以响应四个基本网络中断之一生成PCI中断所需步骤的示例。此示例还列出了服务该中断所需的步骤。LAS1BA remap register before accessing the new window. This ensures the new window mapping has taken effect and subsequent memory accesses will be to the new memory window. In summary, register LAS1RR is the range register corresponding to the size of the PCI window and is read‐only. Register LAS1BA is the writeable base address register. It is used to remap or offset the PCI PIO window to access other sections of the installed memory. The RFM‐5565 firmware prevents the user from entering an invalid Remap Value. The value written must be a multiple of the PCI window size. For example, using a PCI window size of 2 MByte with 64 MByte of installed memory means there are 32 valid base address settings from $00000000 to $03E00000, incrementing by $00200000 (all other bits are masked off when written). Also, a 64 MByte card with a 64 MByte window has no valid base address settings other than the default 0. Since the PCI window size and the Remap register only affect PCI PIO accesses, DMA (Local‐to‐PCI and PCI‐to‐Local) can be used normally to transfer up to $7FFFFF bytes with another location on the PCI bus regardless of the Remap value. Programming 64 3.7 Example of Network Interrupt Handling The following is an example of the steps necessary to set up the RFM‐5565 to generate a PCI interrupt in response to one of the four basic network interrupts. This example also lists the steps necessary to service that interrupt.
