All rights reserved. 31.Mar.2014 Rev.003 www.rohm.com TSZ22111・15・001 BU21024FV-M BU21024FV-M has monitor terminals(XPM, YPM, XNM, YNM) another interface terminals(XP, YP, XN, YN). The monitor terminals are used in touch screen voltage monitor that 4PORT(0x30[2]) set to “0”. The monitor terminals open and 4PORT(0x30[2]) set to “1” If they are not being used. The monitor terminals also helps in increasing the screen’s dynamic range by reducing error due to PCB wiring resistance.
