This example: I2CEEPROM - name of application: main.c
====================================================
Demonstration of talking to an EEPROM on the I2C bus.


Hardware requirements
=====================
Phytec RDK 591 with Philips 591


Software requirements
=====================
Phytec Flash Tools (part of RDK 591)
  www.phytec.com
Raisonance 8051 compiler system - EVAL version sufficient
  www.raisonance.com
or Keil 8051 Compiler System - EVAL version sufficient
  www.keil.com
Optional: Development Assistant-C by RistanCASE
  www.ristancase.ch


Tested using
============

Raisonance 51 Toolset version 6.1.1
Keil C51 Toolset version 6.00


Application description
=============================================
Raisonance specific files have their names prefixed with 'r'.
Keil specific files have their names prefixed with 'k'.
The same source files are used for both compilers.

This program stores a byte in the serial EEPROM then reads it back
complete with error checking and timeout recovery
The program results are output through the UART. Connect using:
9600 baud, 8-N-1, no flow control.

This program does not demonstrate writing whole pages to the EEPROM.
The Serial EEPROM is 4kb in size, therefore valid addresses are 000H - FFFH
eeprom_write_byte and eeprom_read_byte do not return until there is either
an error or a successful storage. Both functions wait up to 22ms for the
EEPROM to be ready using a polling method. The status may be read in the
variable i2c_status and will be I2C_OK or I2C_ERROR
