CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Oscillation Circuit)
4.3.3 OSC3 oscillation circuit (S1C60A16)
The S1C60A16 has built-in the OSC3 oscillation circuit that generates the CPU's sub-clock (Typ. 1 MHz)
for high speed operation and the source clock for the serial interface. The mask option enables selection
of CR or ceramic oscillation circuit.
Figure 4.3.3.1 is the block diagram of the OSC3 oscillation circuit.

Fig. 4.3.3.1 OSC3 oscillation circuit
As shown in Figure 4.3.3.1, the CR oscillation circuit can be configured simply by connecting the resistor
RCR between the OSC3 and OSC4 terminals when CR oscillation is selected. See Chapter 7, "Electrical
Characteristics", for resistance value of RCR.
When ceramic oscillation is selected, the ceramic oscillation circuit can be configured by connecting the
ceramic oscillator (Typ. 1 MHz) between the OSC3 and OSC4 terminals, capacitor CGC between the OSC3
and OSC4 terminals, and capacitor CDC between the OSC4 and VSS terminals. See Chapter 7, "Electrical
Characteristics", for capacitor values of CGC and CDC. To reduce current consumption of the OSC3
oscillation circuit, oscillation can be stopped by the software (OSCC register).
For the S1C60N16 and S1C60L16 (single clock model), do not connect anything to terminals OSC3 and
OSC4.
4.3.4 Switching the system clock (S1C60A16)
In the S1C60A16, the CPU system clock is switched to OSC1 or OSC3 by the software (CLKCHG register).
When OSC3 is to be used as the CPU clock, it should be done as the following procedure using the
software: turn the OSC3 oscillation ON and wait at least 5 msec for oscillation stabilization, then switch
the CPU clock after waiting 5 msec or more.
When switching from OSC3 to OSC1, switch the CPU clock, then turn the OSC3 oscillation circuit off.
OSC1
→ OSC3
OSC3
→ OSC1
1. Set OSCC to "1" (OSC3 oscillation ON).
1. Set CLKCHG to "0" (OSC3
→ OSC1).
2. Maintain 5 msec or more.
2. Set OSCC to "0" (OSC3 oscillation OFF).
3. Set CLKCHG to "1" (OSC1
→ OSC3).
