17.3.4 Monitoring RC Oscillation
The RC oscillator clock (RCCLK) can be output using the secondary function of the P35 pin of Port 3. See Chapter 14,
“Port 3,” for the details of the secondary function of P35.
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 RT1, and the oscillation frequency with reference resistor RS1.
Note:
P35 (RCM) is a monitor pin for oscillation clock.
Please use P35 (RCM) for the evaluation purpose and disable the output while operating in an actual application to
minimize the noise.
