When the on-chip clock generator is used, the STS bits should be set to allow a settling time of at
least 10ms. 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.
