MPC5604S LCD without DCU

I am using MPC5604S. I need to use LCD module to display the temperature. Should I enable DCU module ? will it work alone with LCD module ? Can anyone share a sample code for MPC5604S for LCD module without using DCU module.

If you mean MPC5606S's module called 'LCD Driver', it is for driving monochromatic segment display like for instance this one:

For driving TFT displays, DCU module in needed to use. I have example code for TFT display (i.e. DCU) that is present on MPC5606S-DEMO-V2 showing temperature measured with external temperature sensor:

I have configured LCD module in MPC5604s. When I am connecing the LCD segment pins to CRO I could find a slow rise in the output signal. why is it so and can you suggest any method to rectify this issue.I have configured the port as special function and Pull up enabled, Am I missing any port configuration ?
