(1)
In order to achieve better oscillator accuracy (10 MHz ± 1% or better) than shown, refer to the Oscillator Compensation Guide
Application Report (literature number SPRAB84).
(2)
Frequency range ensured only when VREG is enabled, VREGENZ = VSS.
(3)
Output frequency of the internal oscillators follows the direction of both the temperature gradient and voltage (VDD) gradient. For
example:
Increase in temperature will cause the output frequency to increase per the temperature coefficient.
Decrease in voltage (VDD) will cause the output frequency to decrease per the voltage coefficient.
