5.2 Reduction in Current Consumption by RESET Signal
network connected across V
the STOP mode or when it is being reset. Therefore, for a system to which reducing the current draw is extremely
important, the current path thorough the resistor network must be cut off by an external circuit, when no displaying is
performed, to eliminate unnecessary current flow.
using the the RESET signal level instead of the V
Figure 5–5 shows a circuit which cuts off the current to the resistor network during reset state (RESET = high)
If a resistor network is used to supply the LCD drive reference voltage, some current is drained by the resistor
