Initialization:
Before the LCD controller can accept or display data or text it must be initialized. This is usually
done immediately after the system is powered up. The following chart lists the initialization
commands and the parameters that accompany them along with a brief explanation of the function
of each. Where a parameter is different for a display that differs in resolution from the 240x64
example, the alternate values are also listed.
