Using an External Clock: The PLL circuit requires time to stabilize, so the standby time should
be set to a value of 2 ms or more.
Page 968 of 1458
Set bits STS2 to STS0 so that the standby time is at least 12 ms (the oscillation stabilization
time).
Table 23B-7 shows the standby times for different operating frequencies and settings of bits
STS2 to STS0.
