Characteristics
Refer to the DSP56321 User’s Manual for a detailed description of register reset values.
The total multiplication factor (MF) includes both integer and fractional parts (that is, MF = MFI + MFN/MFD).
The numerator (MFN) should be less than the denominator (MFD).
DPLL lock procedure duration is specified for the case when an external clock source is supplied to the EXTAL pin.
Frequency-only Lock Mode or non-integer MF, after partial reset.
Frequency and Phase Lock Mode, integer MF, after full reset.
