5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Oscillation Circuits and Operating Mode)
5.3.7 Control of oscillation circuit and operating mode
Table 5.3.7.1 shows the control bits for the oscillation circuits and operating modes.
Table 5.3.7.1 Oscillation circuit and operating mode control bits
VDC1, VDC0: 00FF02HD1, D0
Selects the operating mode according to supply
voltage and operating frequency.
Table 5.3.7.2 shows the correspondence between
register preset values and operating modes.

preset values and operating modes
CLKCHG: 00FF02HD3
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 "0" (OSC1 clock).

The VD1 voltage is the value where VSS has been
made the standard (GND).
At initial reset, this register is set to "0" (normal
mode).
OSCC: 00FF02HD2
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
(output port, serial interface and programmable
timer) are to be operated at high speed, OSCC 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, OSCC is set to "0" (OSC3 oscillation
OFF).
