VLSI芯片的SPI连接方法及程序代码，例如它的连接方式，及其不同代码之间的关系-VLSI Solution’s slave VS10xx ICs are typically connected to a microcontroller using two

SPI buses. These buses, which share clock and data pins, are called SCI (Serial Con-trol Interface) and SDI (Serial Data Interface). This document presents seven different

ways to connect VS10xx to a host microcontroller with SPI, with example code and SPI

waveform examples for each way.
