SOSC3: 00FF02H•D2

Controls the ON and OFF settings of the OSC3
oscillation circuit.

When "1" is written: OSC3 oscillation ON
When "0" is written: OSC3 oscillation OFF
Reading:

Valid

When the CPU and some peripheral circuits are to
be operated at high speed, SOSC3 is to be set to "1".
At all other times, it should be set to "0" in order to
reduce current consumption.
At initial reset, SOSC3 is set to "1" (OSC3 oscillation
ON).

CLKCHG: 00FF02H•D3

Selects the operating clock for the CPU.

When "1" is written: OSC3 clock
When "0" is written: OSC1 clock
Reading:

Valid

When the operating clock for the CPU is switched
to OSC3, CLKCHG should be set to "1" and when
the clock is switched to OSC1, CLKCHG should be
set to "0".
At initial reset, CLKCHG is set to "1" (OSC3 clock).

5.4.7 Programming notes

(1) When the high speed CPU operation is not

necessary, you should operate the peripheral
circuits according to the setting outline indicate
below.

• CPU operating clock

OSC1

• OSC3 oscillation circuit

OFF

(When the OSC3 clock is not necessary for
some peripheral circuits.)

(2) Since several msec to several tens of msec are

necessary for the oscillation to stabilize after
turning the OSC3 oscillation circuit ON.
Consequently, you should switch the CPU
operating clock (OSC1 

→

 OSC3) after allowing

for a sufficient waiting time once the OSC3
oscillation goes ON. (The oscillation start time
will vary somewhat depending on the oscillator
and on the externally attached parts. Refer to the
oscillation start time example indicated in
Chapter 8, "ELECTRICAL CHARACTERIS-
TICS".)

(3) When switching the clock from OSC3 to OSC1, be

sure to switch OSC3 oscillation OFF with
separate instructions. Using a single instruction
to process simultaneously can cause a malfunc-
tion of the CPU.

(4) When switching the system clock from OSC3 to

OSC1 immediately after the power is turned on,
it is necessary to wait the OSC1 oscillation to
stabilize before the clock can be switched. The
OSC3 oscillation takes several tens of msec to
several seconds until it has completely stabilized.
(The oscillation start time will vary somewhat
depending on the oscillator and on the externally
attached parts. Refer to the oscillation start time
example indicated in Chapter 8, "ELECTRICAL
CHARACTERISTICS".)
