Hello everyone!
For very first time I need to create a driver for this type of display. The difference at this display is that the interface driving this device is SPI or I2C, not a driver to include in my program. I intend to use SPI communication. So I don't know how to initialize the display. If someone ever works with that type of display I would be very thankful to give me some example code or reference.
Excuse my bad english!

Thx in advance!

You didn't post the full part number of the lcd. Just searching with Google
for NHD-C0216CZ gives this data sheet:
http://www.newhavendisplay.com/specs/NHD-C0216CZ-NSW-BBW-3V3.pdf
The data sheet has pseudo-code for a driver on page 10.
You could translate this to CCS.

There is a driver flow-chart and pseudo-code on pages 33-34 here:

Ok but I met some problems with understanding the notion like:

The P1 and P3 lines are likely some setup code for the i/o ports on
the 8051 microcontroller. You can ignore those lines.

SI is the serial input pin to the lcd. You can use output_low(SI)
and output_high(SI) for those lines.
