RF interrupt on register retention

[ciab_2g4]

Hi, I use nRF24LE1 configured for power down on register retention mode with RFRx active.

When the CPU is on power down i don't have any interrupt from RFIRQ.

Init configuration

IEN1 = 0x22; // interrupt from RTC and RFIRQ

WUCON = 0x0f; // wakeup from RTC and RFIRQ

  void main (void)
  
  {

    Init();

    for(;;)

   {

     PWRDWN = 0x07;

     Delay(10);

     PWRDWN = 0x04;

 }

}

  TICK_ISR()
  {
 

  }

Thank you
