注：出厂配置是安装的所有跳线分流器，引脚7和8除外，目前未使用。寄存器和内存配置开关ABB CMA198占用VME总线上的两个独立地址空间（控制和状态寄存器以及SDRAM内存地址空间）。可以为扩展地址空间（A32）或标准地址空间（A24）设置控制和状态寄存器空间，并将其配置为响应监督、非特权或两种模式的访问。SDRAM存储器空间可以被设置为用于扩展地址空间（A32），并且被配置为响应监督、非特权或两种模式的访问。
注意：为了正常工作，两个地址配置不得相互重叠或系统中的任何其他板，这一点很重要。如果开关为ON，则相关的地址位设置为0。如果开关处于断开状态，则相关的地址位设置为1。在某些情况下，如示例1所示，不使用某些开关。如果在A24空间中配置控制寄存器和状态寄存器，则不使用开关S7，因为地址线A31至A24不用于A24空间。有关设置和配置寄存器和存储器开关的示例，请参阅第41页表2-3至第43页表2-5。

NOTE: The factory configuration is all jumper shunts installed, with the exception of pins 7 and 8, which are currently not used.Registers and Memory Configuration Switches The ABB CMA198 occupies two separate address spaces on the VMEbus (Control and Status Register and SDRAM Memory Address spaces). The Control and Status Register Space can be set-up for Extended Address Space (A32) or Standard Address Space (A24) and configured to respond to either supervisory, nonprivileged or both mode accesses. The SDRAM Memory Space can be set-up for Extended Address Space (A32) and configured to respond to either supervisory, nonprivileged or both mode accesses.
NOTE: It is important that the two address configurations do not overlap each other or any other board in the system in order to work properly. If a switch is ON, the associated Address bit is set to 0. If a switch is OFF, the associated Address bit is set to 1. In some cases, as in example 1, some switches are not used. If the Control and Status Registers are configured in A24 space, switch S7 is not used, since address lines A31 through A24 are not used for A24 space. Refer to Table 2-3 on page 41 through Table 2-5 on page 43, for examples on setting up and configuring the register and memory switches.
