NOTES ON CONTROLLER TRANSFER OF DISPLAY DATA

To accepts the display data (D1 to D318) perfectly, data is divided into three separated transfer operations when

you use the 1/3 duty drive scheme, the data (D1 to D420) is divided into four separated transfer operations when

you use the 1/4 duty drive, and the data (D1 to D106) in one transfer operation when static drive, we recommend

that all of the display data must be transferred within a period of less than 30 ms.
