Acquisition/Lock Time Specifications
bit is set. The resultant waveform can be captured on an oscilloscope and used to determine the typical
lock time for the microcontroller and the associated external application circuit.
e.g.
t_LOCK
t_ACQ
t_AL
Init. low
Signal on port pin
t_TRK Complete and Lock Set
t_ACQ Complete
PLL Configured and switched on
NOTE
The filter capacitor should be fully discharged prior to making any
measurements.
