To switch the transceiver from OFF to AUX mode, the voltage on pin VAUX V
exceed 3.5 V (typically) (see Figure 32). If V
is set to low, DVCC and the power supply for external devices VSOUT are switched on.

After the voltage on pin VSOUT exceeds 2.3 V (typically) and the start-up time of the
XTO is elapsed the output clock on pin CLK is available. Because the enabling of pin
CLK is asynchronous the first clock cycle may be incomplete. N_RESET is set to high if

If the transceiver is in any active mode (Idle, TX, RX, RX_Polling), a positive edge on pin
VAUX and V
1 generates an interrupt. If P_On_Aux is still 1 during the positive edge on pin VAUX no
interrupt is issued. P_On_Aux and the interrupt is deleted after reading the status
register.
