    There are 8 control bits in the touch screen controller (AD7873)

    S 		Start bit, always one.
    A2 - A0	Channel select bits
    MODE	0 => 12 bit resolution, 1 => 8 bit
    SER/DFR#	Single ender/Differential Reference Select bit
    PD1, PD0	Power management bits (usually 10)


From Table 1.

	1 X+ (is this a typo? - is this X- really?)
	2 VBAT,
	3 read X+ (Z1),
	4 read Y- (Z2), 5 => read Y+,
