Using the Mid-Range Enhanced Core PIC16 Devices' MSSP Module for Slave I2C Communication
Many devices in the PICmicro family have a Synchronous Serial Port (SSP) or Master Synchronous Serial Port (MSSP). These peripherals can be used to implement the SPI TM 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 PICmicro devices with the SSP or MSSP modules are used as a Slave device on an I 2 C bus.
