Figure 2. Clock Sources
System Timing
For maximum versatility, the MAXQ2000 generates its
internal system clock from one of five possible sources:
Internal ring oscillator
External high-frequency crystal or ceramic resonator,
using an internal oscillator
External high-frequency clock source
External 32kHz crystal or ceramic resonator, using an
internal oscillator
External 32kHz clock source
A crystal warmup counter enhances operational relia-
bility. Each time the external crystal oscillation must
restart, such as after exiting Stop mode, the device initi-
ates a crystal warmup period of 65,536 oscillations.
This allows time for the crystal amplitude and frequency
to stabilize before using it as a clock source. While in
the warmup mode, the device can begin operation from
the internal ring oscillator and automatically switch
back to the crystal as soon as it is ready.
