5.1 Notes for Low Current Consumption
The S1C621C0 contains control registers for each of the circuits so that current consumption can be low-
ered. These control registers lower the current consumption through programs that operate the circuits at
the minimum levels.
The following text explains the circuits that can control operation and their control registers. Refer to these
when putting programs together.

Control register
HALT instruction
CLKCHG, OSCC

Circuit (and Item)
See Chapter 7, "ELECTRICAL CHARACTERISTICS", for order of current consumption.
CPU
CPU operating frequency
LCD power supply circuit
Remote controller
SVD circuit
Below are the circuit statuses at initial reset.
CPU:
Operating status
CPU operating frequency:
Low speed side (CLKCHG = "0"),
OSC3 oscillation circuit OFF status (OSCC = "0")
LCD power supply circuit:
OFF status (LPWR = "0")
Remote controller:
OFF status (REMCR = REMDC = "0")
SVD circuit:
OFF status (SVDON = "0")
Also, be careful about panel selection because the current consumption can differ by the order of several
A on account of the LCD panel characteristics.
