In order to prevent meaningless displays, it is recommended that the following procedures be followed. The /INH Pin must be set to "LOW" level at the same the power is applied to turn OFF the display. This will then set the SG1/P1 to SG8/P8, SG9 to SG66 and COM1 to COM4 pins to "LOW" level.

When turning ON the power, the logic power supply (VDD) must be first turned ON followed by the LCD Drive Power Supply (VLCD). Conversely, when turning the power OFF, the LCD Drive power supply (VLCD) must first be turned OFF, followed by the logic power supply (VDD). During instances when the Logic and the LCD Driver Block share the same power supply, the power supply can be turned ON or OFF simultaneously. DISPLAY DATA CONTROLLER TRANSFER PT6574 accepts four separate transfer operations of display data -- D1 to D264, therefore it is recommended that the applications must complete all four data transfers within a period of less than 30ms in order to prevent visible reduction of display quality.
