The output power is given in the table
as relative to the maximum available
power, which depends on the actual
antenna impedance.
6. Low Battery Detector and TX Bit Synchronization Command

1 1 0 0 0 0 1 0 dwc 0 ebs t4 t3 t2 t1 t0 C200h
Bit 7 <dwc> Disables the Wake-up timer periodical (every 30 second) calibration if this bit is set.
Bit 5 <ebs> Enables the TX bit synchronization circuit. The data rate must be set by the Data Rate
Command.5
The 5-bit value T of <t4 : t0> determines the threshold voltage V lb of the detector:
V lb= 2.2 V + T * 0.1 V
7. Sleep Command

The effect of this command depends on the Power Management Command. It immediately disables the
power amplifier (if a0=1 and ea=0) and the synthesizer (if a1=1 and es=0). Stops the crystal oscillator
