●Specification of Touch Detection
BU21029GUL executes its touch detection function by outputting an interrupt signal at pin INT once it is able to detect
touch. The circuit diagram of the touch detection function is shown on the following figure.

Figure 4. Touch detection circuit
When the touch panel is connected to the panel interface terminals (XP, XN, YP, YN), pin XP is connected to PVDD
through an internal pull-up resistor inside the IC and pin YN is connected to PGND. During a no-touch state, BU21029GUL
will be on standby. During this time, INT outputs "H" through an internal pull-up resistor. Since pins XP and YN are
connected to the touch screen through contact resistance, the resistance ratio of the internal pull-up resistance and the
touch screen resistance is able to detect the voltage drop at pin XP whenever the screen is touched. This results to an "L"
output at INT.
When touch is detected and pins XP and YP is put to drive state by each scanning operation, the internal pull-up resistance
is disconnected from pin XP and the output of pin INT is held at "L".
