(12) Maximum Allowable Temperature Drift for Continuous Lock is how far the temperature can drift in either direction from the value it was
at the time that the R0 register was last programmed, and still have the part stay in lock. The action of programming the R0 register,
even to the same value, activates a frequency calibration routine. This implies the part will work over the entire frequency range, but if
the temperature drifts more than the maximum allowable drift for continuous lock, then it will be necessary to reload the R0 register to
ensure it stays in lock. Regardless of what temperature the part was initially programmed at, the temperature can never drift outside the
frequency range of -40 °C to 85 °C without violating specifications.
