The transition numbers correspond to
"Basic Application Schematic" on page 495.
The state transition timing is calculated based on the timing of the individual blocks
shown in
temperature, minimum supply voltage, and device parameter variations.

Depends on crystal oscillator setup (CL = 10 pf)
TRX_OFF state indicated by TRX24_AWAKE interrupt
For f
Depends on external capacitor at AVDD (1 µF nom)
Depends on external capacitor at AVDD (1 µF nom)
Transition time is also valid for TX_ARET_ON, RX_AACK_ON
When setting bit SLPTR or TRX_CMD = TX_START, the first
symbol transmission is delayed by 16 µs (PLL settling and
PA ramp up).
