ready to be read. For example a return value of 0x0041 means that ADC pair 6,
AN12 and AN13, and ADC pair 0, AN0 and AN1, are ready to be read.

i2c_init([stream],baud);
stream – optional parameter specifying the stream defined in
#USE I2C.
baud – if baud is 0, I2C peripheral will be disable. If baud is 1, I2C
peripheral is initialized and enabled with baud rate specified in #USE I2C
directive. If baud is > 1 then I2C peripheral is initialized and enabled to
specified baud rate.
Nothing
To initialize I2C peripheral at run time to specified baud rate.
All devices.
#USE I2C
#USE I2C(MASTER,I2C1, FAST,NOINIT)
i2c_init(TRUE); //initialize and enable I2C peripheral to baud
rate specified in //#USE I2C
i2c_init(500000); //initialize and enable I2C peripheral to a
baud rate of 500 //KBPS
