Frequency Registers
Selection of Frequency Registers
Table 4-20.
Table 4-21.
Note:
There is no simple relationship between the frequency registers and the exact frequency. e2v provides a tool to
program them on a production bench.
The FSK modulation is completely integrated. Two registers must be programmed (default F0 and F1) to
allow 0 and 1 transmission.
The frequency register selection depends on the control register programming and on the DATAMSG
pin.
Table 4-22.
in reception mode, only frequency need to be programmed. In transmission mode, two different registers
F0 and F1 or F2 and F3 must be programmed for 0 code and 1 code transmission. The DATAMGS pin
value actually selects the used register. The four registers can also be set to define two channels so that
the AT86RF211S may switch quickly from one channel to another.
