The PLL lock function uses up and down signals from the internal phase detector.
These signals are analyzed synchronously with a clock frequency, depending on the
LDCK bit programming:
Except in cases where compatibility with the former AT86RF211 is mandatory, please
use the PLL lock bit in RF211S mode.
We recommend using the default values indicated in Table 2-18 on page 41.
The data rate (in bps) and the decimal value to be coded in the register are related by
the equation:
The following table gives the programming values of commonly used rates:
Table 2-10.
WPER can be set from 10 ms to 328 seconds with an accuracy of ±20%. A 10 ms period
clock is used for generating this period.
Bits 8 and 7 give a period multiplication factor of 1, 16 or 256 (with two serial by 16 clock
prescalers).
Bits 6 to 0 give the number of cycles of the divided clock from 1 to 128 (counter).
RATE
• N0LD2 triggers the PLL’s unlock condition.
• N1LD2 triggers the PLL’s lock condition.
