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
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 4-11.
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
