Toshiba T6963C manual Initialization bytes, Displayed image, Command Code Parameters Function

Application Note

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.
