Crystal oscillator
Set STS2 to STS0 for a settling time of at least 8 ms. Table 22.3 lists the settling times selected
by these bits at several clock frequencies.
External clock
The STS bits can be set to any value. When 1,024 states (STS2 to STS0 = 101) is selected, the
following points should be noted.
If a period exceeding øp/1,024 (e.g. øp/2,048) is specified when selecting the 8-bit timer,
PWM timer, or watchdog timer clock, the counter in the timer will not count up normally when
1,024 states is specified for the settling time. To avoid this problem, set the STS value just
before the transition to software standby mode (before executing the SLEEP instruction), and
re-set the value of STS2 to STS0 to a value from 000 to 100 directly after software standby
mode is cleared by an interrupt.
2. Recommended values are printed in boldface.
