5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Oscillation Circuits)
5.3.4 OSC3 oscillation circuit
The OSC3 oscillation circuit generates the system
clock when the CPU and some peripheral circuits
(output port, serial interface, programmable timer
and remote controller) are in high speed operation.
This oscillation circuit stops when the SLP instruc-
tion is executed, or the OSCC register is set to "0".
In terms of oscillation circuit types, any one of
crystal oscillation, ceramic oscillation or CR
oscillation can be selected by mask option.
Figure 5.3.4.1 shows the configuration of the OSC3
oscillation circuit.

When crystal or ceramic oscillation circuit is
selected, the crystal or ceramic oscillation circuit are
formed by connecting either a crystal oscillator
(X'tal2) or a combination of ceramic oscillator
(Ceramic) and feedback resistor (Rf) between OSC3
and OSC4 terminals and connecting two capacitors
(CG2, CD2) between the OSC3 terminal and VSS, and
between the OSC4 terminal and VSS, respectively.
When CR oscillation is selected, the CR oscillation
circuit is formed merely by connecting a resistor
(RCR3) between OSC3 and OSC4 terminals.
5.3.5 Switching the CPU clock
You can use either OSC1 or OSC3 as the system
clock for the CPU and you can switch over by
means of software.
You can save power by turning the OSC3 oscilla-
tion circuit off while the CPU is operating in OSC1.
When you must operate on OSC3, you can change
to high speed operation by turning the OSC3
oscillation circuit ON and switching over the
system clock. In this case, since several 100 sec to
several 10 msec are necessary for the oscillation to
stabilize after turning the OSC3 oscillation circuit
ON, you should switch over the clock after
stabilization time has elapsed. (The oscillation start
time will vary somewhat depending on the oscilla-
tor and on the externally attached parts. Refer to
the oscillation start time example indicated in
Chapter 7, "ELECTRICAL CHARACTERISTICS".)
When switching over from the OSC3 to the OSC1,
turn the OSC3 oscillation circuit OFF immediately
following the clock changeover.
Figure 5.3.5.1 indicates the status transition dia-
gram for clock changeover.
