 * Side Effects:    None
 *
 * Overview:        PIC24: if 8-bit data mode is selected, the data appears on 8
 *					data lines.  If 16-bit data mode, the lower 8 bits of data
 *					are written first, followed by the upper 8 bits of data.
 * 					
 * Note:			Use in MASTER mode 1 or 2, MODE[1:0] = 10, 11
