Status Register
1942C–WIRE–06/02
In reception mode, only one frequency needs to be programmed. In transmission mode,
two different registers (F0 & F1), or (F2 & F3) must be programmed for “0” code and “1”
code transmission. The DATAMSG pin value actually selects the used register. The four
registers can also be set to define two channels, so that the AT86RF211 may switch
quickly from a channel to the other.
Example:
FCHANNEL = 868.3 MHz
IF1 = 10.7 MHz
Deviation = ± 4 kHz
Notes:
The STATUS register is used to read the status of internal functions (including the
wake-up function) or the output value of the internal ADC. This register can only be
read.
