The output power is given in the table

as relative to the maximum available

power, which depends on the actual

antenna impedance.

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

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
