Presence detection indicator: 1 = pres-
ence detected; 0 = presence not detect-
ed.
Impedance Sense Value (Bits 30:1): Mea-
sured impedence of the widget. An all ones
value indicates an invalid sense reading
Impedance Sense Value (Bit 0)/Trigger:
Read = Impedance value bit 0
Write 0 = Impedance sense occurs using left
channel
Write 1 = Impedance sense occurs using
right channel
