 * Function:         unsigned int getcSPI1(void)
 *
 * PreCondition:    None
 * Input:           None
 * Output:          the contents of SPIBUF register in byte/hword/word format
 * Side Effects:    None
 * Overview:        This function waits for receive data to be available.
 * 					It will then read single byte/half word/word from SPI bus.
 * Note:            Having byte/hword/word accesses will perform correctly.
 *
 *                  When a new data word has been shifted into shift register SPIxSR and 
 *                  the previous contents of receive register SPIxRXB have not been read
 *                  by the user software, then SPIROV bit (SPIxSTAT<6>) will be set.The 
 *                  module will not transfer the received data from SPIxSR to the SPIxRXB. 
 *                  Further data reception is disabled until the SPIROV bit is cleared. 
 *                  The SPIROV bit is not cleared automatically by the module and must be 
 *                  cleared by the user software.
