使用PIC器件从动IIC通信的SSP和MSSP模块

资料介绍
Many of the PIC
®
microcontroller devices have a
Synchronous Serial Port (SSP) or Master Synchronous
Serial Port (MSSP). These peripherals can be used to
implement the SPI or I
2
C™ communication protocols.
The purpose of this application note is to provide the
reader with a better understanding of the I
2
C protocol
and to show how devices with these modules are used
as a slave device on an I
2
C bus.
For more information on the I
2
C bus specification or the
SSP and MSSP peripherals, you may refer to sources
indicated in the “References” section.
