SPT: When SPT = 1, liquid crystal is driven with 2 split screens. For details, see the “Screen Split Drive
Function” section. This function is not available in the external display interface mode. In this case, make

same data on both normally white and normally black panels. The source output during front, back porch
periods and blank periods during the 2-split-screen display is made in accordance with settings with PT1-0
bits.
