**     Abstract  :
**         This bean "AsynchroSerial" implements an asynchronous serial
**         communication. The bean supports different settings of
**         parity, word width, stop-bit and communication speed,
**         user can select interrupt or polling handler.
**         Communication speed can be changed also in runtime.
**         The bean requires one on-chip asynchronous serial channel.
**     Settings  :
**         Serial channel              : SCI0
**
**         Protocol
**             Init baud rate          : 9600baud
**             Width                   : 8 bits
**             Stop bits               : 1
**             Parity                  : none
**             Breaks                  : Disabled

** ===================================================================
**     Method      :  SCI0_RecvChar (bean AsynchroSerial)
**
**     Description :
**         If any data is received, this method returns one
**         character, otherwise it returns an error code (it does
**         not wait for data). This method is enabled only if the
**         receiver property is enabled.
**         [Note:] Because the preferred method to handle error and
**         break exception in the interrupt mode is to use events
**         <OnError> and <OnBreak> the return value ERR_RXEMPTY has
**         higher priority than other error codes. As a consequence
**         the information about an exception in interrupt mode is
**         returned only if there is a valid character ready to be
**         read.
**     Parameters  :
**         NAME            - DESCRIPTION
**       * Chr             - Pointer to a received character
**     Returns     :
**         ---             - Error code, possible codes:
**                           ERR_OK - OK
**                           ERR_SPEED - This device does not work in
**                           the active speed mode
**                           ERR_RXEMPTY - No data in receiver
**                           ERR_BREAK - Break character is detected
**                           (only when the <Interrupt service>
**                           property is disabled and the <Break
**                           signal> property is enabled)
**                           ERR_COMMON - common error occurred (the
**                           <GetError> method can be used for error
**                           specification)

/*
** ===================================================================
**     Method      :  SCI0_SendChar (bean AsynchroSerial)
**
**     Description :
**         Sends one character to the channel. If the bean is
**         temporarily disabled (Disable method) SendChar method
**         only stores data into an output buffer. In case of a zero
**         output buffer size, only one character can be stored.
**         Enabling the bean (Enable method) starts the transmission
**         of the stored data. This method is available only if the
**         transmitter property is enabled.
**     Parameters  :
**         NAME            - DESCRIPTION
**         Chr             - Character to send
**     Returns     :
**         ---             - Error code, possible codes:
**                           ERR_OK - OK
**                           ERR_SPEED - This device does not work in
