MOTOROLA MVME162-223 嵌入式控制器 用于在SCSI和本地总线之间传递数据

MVME162-223是一种工控系统PLC/DCS模块卡件设备，它是美国MOTOROLA品牌生产的嵌入式控制器。部分参数功能如下：

• 数据保持寄存器：用于在SCSI和本地总线之间传递数据，这些位不受复位的影响。
• 计时器1预加载寄存器：保存滴答计时器预加载值。当计数器达到$FFFF时，将加载此值，如果启用中断，则生成中断。运行时，计数器每6.25µs递增一次。
• 计时器1计数器寄存器：是滴答计数器的输出，读取与计数器更新不同步。
• 计时器2预加载寄存器：保存滴答计时器预加载值，请参阅本章中的勾选1预加载寄存器部分。
• 计时器2计数器寄存器：是滴答计数器的输出，读取与计数器更新不同步。

MVME162-223 is an industrial control system PLC/DCS module card device, which is an embedded controller produced by the MOTOROLA brand in the United States. Some parameter functions are as follows:
Data Holding Register: Used to transfer data between the SCSI and local bus, these bits are not affected by resets.
Timer 1 preload register: saves the preload value of the ticking timer. When the counter reaches $FFFF, this value will be loaded, and if interrupts are enabled, interrupts will be generated. At runtime, the counter increments every 6.25 µ s.
Timer 1 counter register: It is the output of the ticking counter, and the reading is not synchronized with the counter update.
Timer 2 preload register: Save the tick timer preload value, please refer to the check box 1 preload register section in this chapter.
Timer 2 counter register: It is the output of the tick counter, and the reading is not synchronized with the counter update.
