23A.6.3 Setting Oscillation Stabilization Time after Clearing Software Standby Mode
Bits STS2 to STS0 in SBYCR should be set as described below.
Using a Crystal Oscillator: Set bits STS2 to STS0 so that the standby time is at least 8 ms (the
oscillation stabilization time).
Table 23A-5 shows the standby times for different operating frequencies and settings of bits STS2
to STS0.

Using a External Clock: The PLL circuit requires time to stabilize, so the standby time should be
set to a value of 2 ms or more.
