Set bits STS4 to STS0 so that the standby time is at least equal to the oscillation settling time.
Table 20.2 shows the standby times for operating frequencies and settings of bits STS4 to
STS0.
A PLL circuit settling time is necessary. Refer to table 20.2 to set the standby time.
: Recommended time setting when using a crystal resonator.
: Recommended time setting when using an external clock.
