Power-on Timing Controller Information Built-in PT6314 controller. Download specification at http://www.newhavendisplay.com/app_notes/PT6314.pdf Table of Commands M68 Parallel Interface: The PT6314 can interface with the CPU in 4‐bits or 8‐bits. Note that the internal registers are composed of 8 bits. During data transfer in 4‐bit mode, DB4‐DB7 performs the data transfer operation two times, DB0‐DB3 should be tied HIGH or LOW. 4‐bit Data Transfer (M68): 8‐bit Data Transfer (M68): Built‐in Font Table Example Initialization after Power ON Quality Information Test Item Content of Test High Temperature storage Endurance test applying the high storage temperature for a long time.
