REFERENCE FREQUENCY GENERATOR (RFG)
18.4.1
Reference Frequency Generator (RFG) Configuration and Functions
Fig. 18-3 shows the configuration of the reference frequency generator.
As shown in Fig. 18-3, the reference frequency generator divides the frequency of the clock oscillator (8
MHz) to generate the reference frequency “fr” for the PLL frequency synthesizer.
The reference frequency fr can be selected from 6.25, 12.5, and 25 kHz.
Selection of the reference frequency fr is performed using the PLL reference mode select register (at address
13H).
Section 18.4.2 describes the configuration and functions of the PLL reference mode select register.
