I use MSP430FR5969 to control CC1120. After register configuration I put CC1120 in different mode of operations (TX,  RX, SFSTXON, IDLE, XOFF and sleep) and put  MCU in LPM3.

 

I measured the current in all these modes, in sleep mode the current consumption is higher than  that consumed in XOFF mode which is abnormal.

I(XOFF) = 0.2 mA     (0.17 mA in datasheet)

I(sleep) = 0.5 mA     (0.001 mA in datasheet)
