Power-on Timing Controller Information Built-in PT6314 controller. Download specification at http://www.newhavendisplay.com/app_notes/PT6314.pdf Table of Commands Serial Interface: Data can only be written when STB is LOW. The first byte (Start byte) consists of 8 bits. Bits 1 through 5 are Synchronous bits, bit 6 is R/W, bit 7 is RS, bit 8 is LOW. R/W is HIGH to read from the display, or LOW to write data to the display. RS is HIGH to read/write Data, or LOW to read/write an Instruction. The following byte or bytes is the 8‐bit instruction or data sent to/from the display.
