PD<2:0>: Pen-Down State bits (action taken upon pen down).
000 = No touch report
001 = Touch report with P=0
010 = Touch report with P=1
011 = Touch report with P=1, then touch report with P=0
100 = Touch report with P=0, then touch report with P=1, then touch report with P=0
101 = Touch report with P=0, then touch report with P=1
PM<1:0>: Pen Movement State bits (action taken upon pen movement).
00 = No touch report
01 = Touch report with P=0
10 = Touch report with P=1
PU<2:0>: Pen-Up State bits (action taken upon pen up).
000 = No touch report
001 = Touch report with P=0
010 = Touch report with P=1
011 = Touch report with P=1, then touch report with P=0
100 = Touch report with P=0, then touch report with P=1, then touch report with P=0
101 = Touch report with P=0, then touch report with P=1
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
