DPLL_ENABLE 

R 

0*, 1 

This bit indicates that the DPLL controller has enabled the DPLL 

29 

AGC_RFOFF_DET 

R 

0*, 1 

This bit indicates than the AGC has detected the   external RF-
Field was switched off while transmitting   in SL-ALM mode. 

Note

: Only valid if the detection mode is enabled with   the 

register bit-field AGC_RF_DETECT_SEL. 

28 

CRC_OK 

R 

0, 1 

This bit indicates the status of the actual CRC calculation. If 1 
the CRC is correct, meaning the CRC register has the value 0 
or the residue value if inverted CRC is used. 

Note

: This flag should only by evaluated at the end of a 

communication

25 

TX_RF_STATUS 

R 

0*, 1 

If set to 1 this bit indicates that the drivers are turned on, 
meaning an RF-Field is created by the device itself 

24 

RF_DET_STATUS 

R 

0*, 1 

If set to 1 this bit indicates that an external RF-Field is detected
