(1) Oscillator frequency will vary over temperature, see
Figure 4-10. To compensate for oscillator temperature drift, see the
Oscillator Compensation Guide and the controlSUITE™ example, Example_2803xOscComp.c.
(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 (V
DD) 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.
