CHAPTER 6 CLOCK MODULATOR
6.3.2
Clock Modulation Parameter Register (CMPR)
The Modulation Parameter Register (CMPR) determines the modulation degree in
frequency modulation mode.
■
Modulation Parameter Register
Figure 6.3-3 Modulation Parameter Register
•
The modulation parameter determines the degree of modulation and the maximal and minimal occurring
frequencies in the modulated clock. Please refer to the application note for a description of an approach
to select the optimal setting.
•
Each set of possible modulation parameters refers to a particular PLL frequency. The PLL frequency
and the selected parameter must match. Please refer to Table 6.3-3.
•
The modulation parameter affects only the frequency modulation mode. Phase modulation mode has a
fixed setting which cannot be changed.
Note:
The modulation parameter must be changed only when the modulator is disabled and the RUN flag
is "0" (FMOD=0, FMODRUN=0).
