After the voltage on pin VSOUT exceeds 2.3V (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

If the transceiver is in any active mode (IDLE, AUX, RX, RX_Polling, TX), a positive edge on pin
PWR_ON sets Power_On to “1” (after T
erates an interrupt. If Power_On is still “1” during the positive edge on pin PWR_ON no interrupt
is issued. Power_On and the interrupt are deleted after reading the status register.
During Power_On = 1, the bits VSOUT_EN and CLK_ON in control register 3 are set to “1”.
