■ Evaluation mode
In case of evaluating a Touch Screen function of the AK4186EN, it is necessary to connect the Touch Screen
with J1 terminal. Regarding pin assignment of J1, refer to Table 2, Table 3 or circuit diagram in this
manual. As for the AK4186EN’s register definitions, refer to datasheet of the AK4186.
Applicable Evaluation Mode
(1) 4-Wire Touch Screen position, pressure measurement and evaluation of A/D using the
analog input terminal.
(2) 5-Wire Touch Screen position measurement.
(1-1) 4-Wire Touch Screen position and pressure measurement.
4-wire resistive touch screen must be connected to J1.
The pin assignment of J1 is shown on Table 2.
