Low Power Mode
When LP bit is 1 and the EXT pin is low (without an extended driver), the HD66710 operates in low
power mode. In 1-line display mode, the HD66710 operates on a 4-division clock, and in 2-line or 4-line
display mode, it operates on 2-division clock. So, instruction execution takes four times or twice as long.
Notice that in this mode, display shift and scroll cannot be performed. Clear display shift with the return
home instruction, and the horizontal scroll quantity.
