/*******************************************************************************
* Function Name: SPI_PutArray
********************************************************************************
*
* Summary:
* Write available data from ROM/RAM to the TX buffer while space is available
* in the TX buffer. Keep trying until all data is passed to the TX buffer.
*
* Parameters:
* *buffer: Pointer to the location in RAM containing the data to send
* byteCount: The number of bytes to move to the transmit buffer.
*
* Return:
* None.
*
* Side Effects:
* Will stay in this routine until all data has been sent. May get locked in
* this loop if data is not being initiated by the master if there is not
* enough room in the TX FIFO.
*
* Reentrant:
* No.
*
