All rights reserved. 【 ECh : XY matrix setting】 Name: POS_MODE Address: ECh Description: Setting when two or more sensor are displayed to the first origin and position is detected. XY : This selects between two matrix configurations. 1 = X axis →SIN [10 : 5] , Y axis → SIN [11:4:12:3:13:2:14:1:15:0] 0 = X axis →SIN [0 : 7] , Y axis → SIN [8:15] POS_EN : The position tracking enable Enables the condition under which the position tracking is made effective. 1=When either of sensor exceeds the threshold, the data of the position tracking is made effective. If all registers do not exceed the threshold, the data of the position tracking is (POSX,POSY) = (0,0). 0=the position is detected regardless of the level of the sensor data, and data is made effective. Initial state: When either of sensor exceeds the threshold, the positional detection data is made effective (=1).
