 * Function:        void putsSPI1(unsigned int length, unsigned int *wrptr)
 *
 * PreCondition:    None
 * Input:           length	- length of bytes/words to be written
 * 					wrptr	- address of buffer storing the data to be transmitted.
 * Output:          None
 * Side Effects:    None
 * Overview:        This function writes the specified length of data words/bytes
 * 					from the specified buffer.
 * Note:            wrptr is considered to be 8/16/32 bits data pointer, according to the
 * 					current SPI mode!
