To switch the transceiver from OFF to IDLE mode, pin Tn must be set to “0” (maximum

devices VSOUT.
If V
sets the status bit STn to “1” and an interrupt is issued (T
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 asynchro-
nous, the first clock cycle may be incomplete. N_RESET is set to high if V
(typically) and the XTO is settled.

Indicates that the transceiver was woken up by pin PWR_ON (rising edge on pin
PWR_ON). During Power_On = 1, the bits VSOUT_EN and CLK_ON in control register 3
