**     Project   : LM75A
**     Processor : MC9S08QE8CFM
**     Beantype  : InternalI2C
**     Version   : Bean 01.196, Driver 01.20, CPU db: 3.00.026

**     Abstract  :
**          This bean encapsulates the internal I2C communication 
**          interface. The implementation of the interface is based 
**          on the Philips I2C-bus specification version 2.0. 
**          Interface features:
**          MASTER mode
**            - Multi master communication
**            - The combined format of communication possible 
**              (see "Automatic stop condition" property)
**            - 7-bit slave addressing (10-bit addressing can be made as well)
**            - Acknowledge polling provided
**            - No wait state initiated when a slave device holds the SCL line low
**            - Holding of the SCL line low by slave device recognized as 'not available bus'
**            - Invalid start/stop condition detection provided
**          SLAVE mode
**            - 7-bit slave addressing
**            - General call address detection provided
**     Settings  :
**         Serial channel              : IIC
**
**         Protocol
**             Mode                    : MASTER

/*
** ===================================================================
**     Method      :  I2C1_SendChar (bean InternalI2C)
**
**     Description :
**         When working as a MASTER, this method writes one (7-bit
**         addressing) or two (10-bit addressing) slave address
**         bytes inclusive of R/W bit = 0 to the I2C bus and then
**         writes one character (byte) to the bus. The slave address
**         must be specified before, by the "SelectSlave" or
**         "SelectSlave10" method or in the bean initialization
**         section, "Target slave address init" property. If
**         interrupt service is enabled and the method returns
**         ERR_OK, it doesn't mean that transmission was successful.
**         The state of transmission is obtainable from
**         (OnTransmitData, OnError or OnArbitLost) events. 
**         When working as a SLAVE, this method writes a character
**         to the internal output slave buffer and, after the master
**         starts the communication, to the I2C bus. If no character
**         is ready for a transmission (internal output slave buffer
**         is empty), the Empty character will be sent (see "Empty
**         character" property).
**     Parameters  :
**         NAME            - DESCRIPTION
**         Chr             - Character to send.
**     Returns     :
**         ---             - Error code, possible codes:
**                           ERR_OK - OK
**                           ERR_SPEED - This device does not work in
**                           the active speed mode
**                           ERR_DISABLED -  Device is disabled
**                           ERR_BUSY - The slave device is busy, it
**                           does not respond by an acknowledge (only
**                           in master mode and when interrupt
**                           service is disabled)
**                           ERR_BUSOFF - Clock timeout elapsed or
**                           device cannot transmit data
**                           ERR_TXFULL - Transmitter is full (slave
**                           mode only)
**                           ERR_ARBITR - Arbitration lost (only when
**                           interrupt service is disabled and in

**     Method      :  I2C1_RecvChar (bean InternalI2C)
**
**     Description :
**         When working as a MASTER, this method writes one (7-bit
**         addressing) or two (10-bit addressing) slave address
**         bytes inclusive of R/W bit = 1 to the I2C bus, then reads
**         one character (byte) from the bus and then sends the stop
**         condition. The slave address must be specified before, by
**         the "SelectSlave" or "SelectSlave10" method or in bean
**         initialization section, property "Target slave address
**         init". If interrupt service is enabled and the method
**         returns ERR_OK, it doesn't mean that transmission was
**         finished successfully. The state of transmission must be
**         tested by means of events (OnReceiveData, OnError or
**         OnArbitLost). In case of successful transmission,
**         received data is ready after OnReceiveData event is
**         called. 
**         When working as a SLAVE, this method reads a character
**         from the input slave buffer.

**       * Chr             - Received character.

**                           ERR_SPEED - This device does not work in

**                           ERR_DISABLED -  Device is disabled
**                           ERR_BUSY - The slave device is busy, it
**                           does not respond by the acknowledge
**                           (only in master mode and when interrupt
**                           service is disabled)
**                           ERR_BUSOFF - Clock timeout elapsed or

**                           ERR_RXEMPTY - No data in receiver (slave
