1 Overview
The Tower LCD RGB Module (TWR-LCD-RGB) adds a side mounting TFT WQVGA Display to the Freescale Tower System. It can be used with Tower Processor Modules featuring an RGB interfacing LCD Controller.
The TWR-LCD-RGB features a 4.3WQVGA TFT LCD Display with touch sensitive overlay. The LCD interfaces to the Tower System through a 24-bit RGB interface. The 4-wire resistive touch overlay can interface directly with a compatible Tower Processor Module using GPIO enabled ADC lines, or can offload the resistive touch sensing to the on-board Xtrinsic Touch Sensing Platform (CRTouch).

3 Hardware Features
This section provides more details about the hardware specific features and functionality of the TWR­LCD-RGB.
3.1 Tower System connection
The TWR-LCD-RGB is designed to interface with the secondary side of the Freescale Tower System. The TWR-LCD-RGB comes pre-attached to an additional TWR-SELE (Secondary Elevator). The LCD module can be detached from the included TWR-SELE, but it is recommended that the modules remain attached to avoid any damage to the LCD glass when attempting to reconnect the modules. For Tower System assemblies that require use of the TWR-LCD-RGB, use the included pre-assembled TWR-LCD-RGB + TWR-SELE.
