LC oscillation control

The oscillation circuit can be turned ON/OFF by the oscillation control bit. Oscillation is stopped during the

period in which the characters are not displayed, to reduce the power consumption.

Nothing can be written to the video RAM while the oscillation is stopped. To write data to the video RAM,

be sure to turn ON oscillation.
