the frequency synthesizer, enable receive
mode, enable transmit mode and other
functions.
The command strobes are issued by
writing to the RFST SFR register. The list
of all strobe commands which are defined
is given in Table 56.
SIDLE
Default state when the radio is not
receiving or transmitting. Typ.
current consumption in radio:
1.8mA.
Idle
Used for calibrating frequency
SCAL

Transitional state. Typ. current
consumption in radio: 7.6mA.
Frequency synthesizer is on,
ready to start transmitting.
Transmission starts very

optional calibration,
settling
Frequency synthesizer is turned on, can optionally be
calibrated, and then settles to the correct frequency.
Transitional state. Typ. current consumption in radio:
7.6mA.
