Power Management Command
Bit 5 <ex>:
Enables the the crystal oscillator.
Bit 4 <es>:
Enables the synthesizer.
Bit 3 <etr>:
Enables the power amplifier. If the ex and es bit is not set, it switches on the crystal oscillator and the
synthesizer as well.
In FIFO mode (bit fe is set in the FIFO Setting Command) setting this bit will roll out the content of the FIFO.
Bit 2 <eb>:
Enables the low battery detector.
Bit 1 <et>:
Enables the wake-up timer.
Bit 0 <dc>:
Disables the clock output buffer.
The constant C is determined by
the selected band as:
Frequency Setting Command
The 12-bit parameter of the Frequency Setting
Command has the value F. The value F
should be in the range of 96 and 3903. When F is out
of range, the previous value is kept. The synthesizer
center frequency f
0
can be calculated as:
f
0
= 8 * 10 MHz * (C + F/4000)

Transmitter FIFO Write Command
With this command, the controller can write databits to the transmitter FIFO. Bit (fe) must be set in the FIFO Setting Command.
