Clock Generating Circuit
Clock Generating Circuit
Example of oscillator circuit
Table 1.10.1. Main clock and sub-clock generating circuits
Figure 1.10.1. Examples of main clock
Figure 1.10.2. Examples of sub-clock
The clock generating circuit contains two oscillator circuits that supply the operating clock sources to the
CPU and internal peripheral units.
Use of clock
Usable oscillator
Pins to connect oscillator
Oscillation stop/restart function
Oscillator status immediately after reset
Other
Figure 1.10.1 shows some examples of the main clock circuit, one using an oscillator connected to the
circuit, and the other one using an externally derived clock for input. Figure 1.10.2 shows some examples
of sub-clock circuits, one using an oscillator connected to the circuit, and the other one using an externally
derived clock for input. Circuit constants in Figures 1.10.1 and 1.10.2 vary with each oscillator used. Use
the values recommended by the manufacturer of your oscillator.
Note: Insert a damping resistor if required. The resistance will vary depending on the oscillator and the oscillation drive

When the oscillation drive capacity is set to low, check that oscillation is stable. Also, if the oscillator manufacturer's
data sheet specifies that a feedback resistor be added external to the chip, insert a feedback resistor between X
and X
