The radio transceivers SLEEP state is left by releasing pin SLP_TR to logic low. This restarts the
XOSC and DVREG. After t TR2 = 380 μs (typ.) the radio transceiver enters TRX_OFF state. The
internal clock signal is available and provided to pin 17 (CLKM), if CLKM was enabled.
This procedure is similar to the Power-On Procedure. However the radio transceiver continues
the state change automatically to the TRX_OFF state. During this the filter-tuning network (FTN)
calibration is performed. Entering TRX_OFF state is signaled by IRQ_4 (AWAKE_END), if this
interrupt was enabled by the appropriate mask register bit.

PLL_ON and RX_ON States
The transition from TRX_OFF to PLL_ON and RX_ON mode is shown in Figure 7-5 on page 40 .

Note:
If TRX_CMD = RX_ON in TRX_OFF state RX_ON state is entered immediately, even if the PLL
has not settled.
In TRX_OFF state, entering the commands PLL_ON or RX_ON initiates a ramp-up sequence of
the internal 1.8V voltage regulator for the analog domain (AVREG). RX_ON state can be
entered any time from PLL_ON state regardless whether the PLL has already locked, which is
indicated by IRQ_0 (PLL_LOCK).
