Table 10 through Table 12 describe the voltage/frequency
requirements for the ADSP-BF534/ADSP-BF536/ADSP-BF537
processor clocks. Take care in selecting MSEL, SSEL, and CSEL
ratios so as not to exceed the maximum core clock and system
clock. Table 13 describes phase-locked loop operating
conditions.
