5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Notes for Low Current Consumption)
5.15 Notes for Low Current
Consumption
The E0C88832/88862 can turn circuits, which
consume a large amount of power, ON or OFF by
control registers.
You can reduce power consumption by creating a
program that operates the minimum necessary
circuits using these control registers.

Next, which circuit systems' operation can be
controlled and their control registers (instructions)
are explained. You should refer to these when
programming.
See Chapter 7, "ELECTRICAL CHARACTERIS-
TICS" for the current consumption.
