//**********************************************************************
//* DESCRIPTION:
//* This file contains a simple test routines for lib24c16 library

//**********************************************************************
//* FUNCTIONS DECLARED:
//* void main (void);
//**********************************************************************
//* NOTES:
//* you need to define the port pins where the memory is connected like
//* this:
//* bit	at	0x90	SCK; // P1_0 = EEPROM SCK
//* bit at	0x91	SDA; // P1_1 = EEPROM SDA
//*
//* - For parts other than 24c16, 'page' must be set according to the
//*   logical values in pins A0, A1 & A2 (see particular datasheet)
//* - Remember the 10mS busy time in writing cycle
//* - The routines closely resembles the assembler code of the AN
//**********************************************************************
//* COMPILE TIME OPTIONS: dcc.exe test.c lib24c16.rel
//* DEBUG OPTIONS: None
//**********************************************************************
//* TO DO:
//*			- create a conditional to select the read or the write
//*			  routine
//*         - add a delay routine to use both read and write
