20.4.3
Bits STS2 to STS0 in SYSCR and bits DIV1 and DIV0 in DIVCR should be set as follows.
Crystal Resonator: Set STS2 to STS0, DIV1, and DIV0 so that the waiting time (for the clock to
stabilize) is at least 7 ms. Table 20.3 indicates the waiting times that are selected by STS2 to
STS0, DIV1, and DIV0 settings at various system clock frequencies.
