INTERNAL POWER CIRCUITS
Figure 14
The internal power supply circuits generate the voltage levels necessary to drive liquid
crystal driver circuits with low-power consumption and the fewest components. There are
voltage converter (V/C) circuits, voltage regulator (V/R) circuits, and voltage follower (V/F)
circuits. They are valid only in master operation and controlled by “Power Control”
instruction. For details, refers to "Instruction Description".
