The power-on procedure to P_ON state is shown in Figure 5-3.
Figure 5-3. Power-on Procedure to P_ON State
When the external supply voltage (V
transceiver enables the crystal oscillator (XOSC) and the internal 1.8 V voltage
regulator for the digital domain (DVREG). After t
at pin 17 (CLKM) at a default rate of 1 MHz. If CLKM is available, the SPI has already
been enabled and can be used to control the transceiver. As long as no state change
towards state TRX_OFF is performed, the radio transceiver remains in P_ON state.
The wake-up procedure from SLEEP state is shown in Figure 5-4.
Figure 5-4. Wake-up Procedure from SLEEP State
The radio transceiver’s SLEEP state is left by releasing pin SLP_TR to logic low. This
restarts the XOSC and DVREG. After t
The internal clock signal is available and provided to pin 17 (CLKM) if enabled.
This procedure is similar to power-on, however, the radio transceiver automatically
ends in 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.
The transition from TRX_OFF to PLL_ON or RX_ON state and further to RX_ON or
PLL_ON is shown in Figure 5-5.
