Chapter 5. SPI Master Communications
5.1
5.2
INTRODUCTION
This chapter describes the SPI Master Communications mode. SPI data and com-
mands can be entered using a Basic Communications window or by creating Script
Commands.
It is assumed that the user is familiar with the SPI protocol. For more information see:
An SPI tutorial is available on the Microchip Technology web site. Click on the links:
