C™ Slave Communications
5.1 INTRODUCTION
This chapter describes I
2
C Slave Communications. The I
2
C Slave mode allows you to
mimic an I
2
C slave by responding to standard Read, Write and Receive commands.
You can mimic an I
2
C slave device from either the PICkit Serial Analyzer PC interface
(Interactive mode), or from the PICkit Serial Analyzer itself (Auto mode).
Additionally, you can run the Interactive mode from either the Basic Communications
page, or from the I
2
C Slave Profile page.
It is assumed that the user is familiar with the I
2
C protocol. For more information see:
• The I
2
C Bus Specification Version 2.1 January 2000 is available from NXP
Semiconductor (formerly Philips Semiconductor) web site at:
