+/// !Purpose
+///
+/// Interface for configuration the Segment LCD Controller (SLCDC) peripheral.
+///
+/// !Usage
+///
+/// -# Initializes the Segment LCD controller using SLCDC_Configure().
+/// -# Clears the SLCD display buffer using SLCDC_Clear().
+/// -# Enable & disable SLCD controller using SLCDC_Enable() and SLCDC_Disable().
+/// -# Enables & disable the SLCD low power mode using SLCDC_EnableLowPowerMode () 
+/// and SLCDC_DisableLowPowerMode().   
+/// -# Adjusts the frame frequency using SLCDC_SetFrameFreq().
+/// -# Sets the display mode (normal/force off/force on/blinking) using 
+/// SLCDC_SetDisplayMode().
+/// -# Adjusts the display blinking frequency using SLCDC_SetBlinkFreq().
+/// -# Enables & disable the selected SLCDC interrupt sources using
+/// SLCDC_EnableInterrupts() and SLCDC_DisableInterrupts().
