This anomaly applies to IC Rev. Revision 2, build codes QDAA-G00.
Supply current is increased in Power-down state.
The device is in Power-down state, and the CSN, RX_EN, TX_EN, MODE, SCK, MOSI, or ANT_SEL pin is set high.
The supply current may increase up to 500 µA per pin set high.
Pull the CSN, RX_EN, TX_EN, MODE, SCK, MOSI, and ANT_SEL pins low in Power-down state. Pull the CSN pin high together with the PDN pin when changing to Program state.
