A couple of typical setup examples for the TouchMode

are as follows:

• Report a pen down P=1 on initial touch, followed

by reporting a stream of pen downs P=1 during

the touch, followed by a final pen up P=0 on touch

release. TouchMode = 0b01010001 = 0x51

• Report a pen up P=0 then a pen down P=1 on

initial touch, followed by reporting a stream of pen

downs P=1 during the touch, followed by a final

pen up P=0 on touch release. TouchMode =

0b10110001 = 0xB1
