communication interface circuit 通信接口电路;[通信分界面电路] A peripheral device programmed by the CPU to operate using virtually any serial data-transmission technique currently in use. One communication interface circuit is the universal synchronous/asynchronous receiver/transmitter(USART). It will typically have a speed of 4,000 kilobits per second for synchronous operation and 250 kilobits per second for asynchronous operation. 用来实现串行数据传送的可由CPU编程的一种外围电路。通用同步/异步、接收/发送器(USART)是通信接口 电路之一,其同步工作方式的典型速度为每秒4兆位;异步工作方式的典型速度是每秒25万位。 |
