Not tested in production. 3. “Min” means the lowest value where the pin is guaranteed to be read as high. 4. Although each I/O port can under non-transient, steady state conditions sink more than the test conditions, the sum of all IOL (for all ports) should not exceed 60 mA. If I exceeds the test condition, V may exceed the related specification. Pins are OL OL not guaranteed to sink current greater than the listed test condition. 5. Although each I/O port can under non-transient, steady state conditions source more than the test conditions, the sum of all I (for all ports) should not exceed 60 mA. If I exceeds the test condition, V may exceed the related specification. Pins OH OH OH are not guaranteed to source current greater than the listed test condition. 6. Measured with all I/O modules turned off (PRR = 0xFF). 1.3Clock Characteristics1.3.1Accuracy of Calibrated Internal Oscillator It is possible to manually calibrate the internal oscillator to be more accurate than default factory calibration. Note that the oscillator frequency depends on temperature and voltage. Voltage and temperature characteristics can be found in Figure 2-53 on page 32, Figure 2-54 on page 33, Figure 2-55 on page 33, and in Figure 2-56 on page 34. Table 1-2.
