7.12.10 TouchMode Register (offset 0x0C)
The TouchMode register configures the action taken for various touch states.
There are three states of touch for which the controller touch reporting action can be independently controlled.
Touch States:
Every touch report include a “P” (Pen) bit that indicates the pen state.
R = Readable bit, W = Writable bit, U = Unimplemented bit read as ‘0’
Bit 7
bit 7-5 PD<7:5>: Pen Down State bits (action taken upon pen down).
bit 4-3 PM<4:3>: Pen Movement State bits (action taken upon pen movement).
bit 2-0 PU<2:0>: Pen Up State bits (action taken upon pen up).
A couple of typical setup examples for the TouchMode are as follows.

1) Pen down (initial touch)
2) Pen Movement (touch movement after initial touch)
3) Pen Up (touch release)
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
User defined 0-3 touch reports, with selectable pen states.
User defined no touch reports or streaming touch reports, with selectable pen states.
User defined 0-3 touch reports, with selectable pen states.
