C (final testing). Both pre-testing and final testing use correlated
test conditions to cover the specified temperature and power supply voltage range.
[2]
This parameter is not part of production testing or final testing, hence only a typical value is stated.
[3]
Oscillator start-up time depends on the quality of the crystal. For most crystals it takes about 1000 clock pulses until the clock is fully
stable.
[4]
Duty cycle clock should be as close as possible to 50%.
