Clock-Generating Circuit
1.2.5.2 Software Reset
Writing a “1” to bit 3 of the processor mode register 0 (address 000416) applies a (software) reset to
the microcomputer. A software reset has almost the same effect as a hardware reset with the following
exceptions:
The contents of internal RAM are preserved
USB registers (030016 to 033C16), USB attach/detach register (001F16), USB control register
(000C16), and Frequency synthesizer related registers (03DB16-03DF16) values are preserved.
1.2.6 Clock-Generating Circuit
The clock-generating circuit contains one oscillator circuit that supplies the operating clock sources to
the CPU and internal peripheral units. Table 1.5 shows the main clock generating circuits.
Table 1.5:
Main clock-generating circuits
Figure 1.11 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. Circuit constants in Figure 1.11 vary
with each oscillator used. Use circuit constant values recommended by the oscillator manufacturer.

(Note)
Note: Insert a damping resistor if required. The resistance will vary depending on the oscillator and the oscillation drive
capacity setting. Use the value recommended by the maker of the oscillator.
When the oscillation drive capacity is set to low, check that oscillation is stable.
