每个器件都有一个八位CMOS移位寄存器和CMOS控制电路，八个CMOS数据锁存，八个双极电流吸收达林顿输出驱动器。
Each device has an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking Darlington output drivers.
之后，驾驶员命令设备来完成其工作(通过操纵其寄存器)和直接在设备传送输出数据在存储器中分配的缓冲区。
Then the driver commands the device to do its job (by manipulating its registers) and the device transfers output data directly to the allocated buffer in the memory.
输出数据通过串行或并行端口从输出寄存器中存取，这可实现与现代微控制器和数字信号处理器的轻松、高速接口。
The output data is accessed from the output register through a serial or parallel port. This offers easy, high speed interfacing to modern microcontrollers and digital signal processors.
