When the on-chip clock generator is used, the STS bits should be set to allow a settling time of at
least 10 ms. Table 12-3 lists the settling times selected by these bits at several clock frequencies
and indicates the recommended settings.
When the chip is externally clocked, the STS bits can be set to any value. The minimum value
(STS2 = STS1 = STS0 = 0) is recommended.

Notes:
1. All times are in milliseconds.
2. Recommended values are printed in boldface.
12.3 Sleep Mode
The sleep mode provides an effective way to conserve power while the CPU is waiting for an
external interrupt or an interrupt from an on-chip supporting module.
