Table 9. Frequency Registers
Note:
•
The FSK modulation is completely integrated. Two registers have to 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:
There is no simple relationship between frequency registers and the exact frequency. Atmel
provides a tool to program them on a production bench.
