Power control 1 (R03h) (POR = 6A64h)
DCT[3:0]: Set the step-up cycle of the step-up circuit for 8-color mode (CM = V
driving ability of the step-up circuit increases, but its current consumption increases too. Adjust the cycle taking into
account the display quality and power consumption.
BT[2:0]: Control the step-up factor of the step-up circuit. Adjust the step-up factor according to the power-supply
voltage to be used.
