LCD
The DEMO9S08LG32 provides a 4 x 40 custom LCD glass connected directly to the target
MCU. Refer to the MC9S08LG32 Reference Manual for details on use and configuration.
A row of option jumpers located below the LCD module allows each LCD signal to be
disconnected from the associated LCD input. This allows multiplexed signal functionality to be
used without affecting the LCD module.
The LCD Enable Option Header allows the user to disable any LCD signal to the LCD. This
allows any signal to be used for a multiplexed function with out affecting the LCD. Figure 15,
at the end of this document, shows the relation between target MCU signals and LCD glass
pins through the JP1 option header. Installing a shunt at any position enables the LCD signal
to the LCD. Removing a shunt at any position disconnects the LCD signal from the LCD.
Contrast
LCD contrast control is controlled by the VLL3_SEL option header. This option header applies
either fixed or variable LCD contrast. Variable contrast control requires the target board be
powered from an external +12V power supply connected to VIN.
