24.3.4 Monitoring RC Oscillation
The RC oscillator clock (RCCLK) can be output using the secondary function of the P05. See Chapter 17, “Port
0,” for the details of the secondary function of P05.
Monitoring RC oscillation is useful for checking the characteristics of the RC oscillator circuit. That is, the
relationship between a sensor, such as a thermistor, and the oscillation frequency can be measured. For instance,
the coefficient for conversion from the above-described nA1 value to a temperature indication value can be
obtained by checking the relationship between the ambient temperature of a thermistor-incorporated RC
oscillator circuit, the oscillation frequency with thermistor RT0, and the oscillation frequency with reference
resistor RS0.
[Note]
P05 (RCM) is a monitor pin for oscillation clock. The Channel 0 and Channel 1 share the monitor pin.
Use P05 (RCM) pin for the evaluation purpose and disable the output while operating in an actual application
to minimize the noise.
