NRF24L01 configuration with external PA & LNA

[RPi23]

Hi, what would be the status of VDD_PA when CSN is high (Power Down mode)? Will it be LOW or Floating/High Impedance?

I know VDD_PA changes to high (1.8 V) or low based on the PRIM_RX bit. But how does this change based on PWR_UP bit?

Thanks in advance..

VDD_PA is the power supply to the internal PA. It will be 1.8 V when the TX is active and 0 V in all other states. It never float.
