Add R/W
The integer part (N) is determined by fb[4:0]. Additionally, the output frequency can be halved by connect-
ing a ÷2 divider to the output. This divider is not inside the loop and is controlled by the hbsel bit in "Regis-
ter 75h. Frequency Band Select". This effectively partitions the entire 240–960 MHz frequency range into
two separate bands: High Band (HB) for hbsel = 1, and Low Band (LB) for hbsel = 0. The valid range of
fb[4:0] is from 0 to 23. If a higher value is written into the register, it will default to a value of 23. The integer
part has a fixed offset of 24 added to it as shown in the formula above. Table 23.3 demonstrates the selec-
tion of fb[4:0] for the corresponding frequency band.
After selection of the fb (N) the fractional component may be solved with the following equation:
fb and fc are the actual numbers stored in the corresponding registers.
