Abstract
This application note describes how to build a reference system for the On-Chip Peripheral Bus Inter IC (OPB IIC) core using the IBM PowerPC ™ 405 Processor (PPC405) based embedded system in the ML403 Embedded Development Platform. The reference system is Base System Builder (BSB) based. An IIC primer is given and an OPB IIC register reference is provided. The Xilinx Microprocessor Debugger (XMD) commands are used for verifying that the OPB IIC core operates correctly. Several software projects illustrate how to configure the OPB IIC core, set up interrupts, and do read and write operations. Some of the software projects interface the OPB IIC to the MicroChip 24LC04B serial EEPROM with an IIC interface, while others interface to the TotalPhase Aardvark Adapter, which provides IIC master and slave functionality. The procedure for using ChipScope ™ to analyze OPB IIC functionality is provided. The steps used to build a Linux kernel using MontaVista are listed. Simulation output files for analyzing basic IIC transactions are provided.
