How can I set output power of NRF51422 to +4dBm?

Question

Is there any API can I use?

In proprietary mode, change the register for TX power as below: 
 NRF_RADIO->TXPOWER = (RADIO_TXPOWER_TXPOWER_Pos4dBm << RADIO_TXPOWER_TXPOWER_Pos); 
 Good examples for how to change the radio registers per the nRF51 RM can be found in the examples folder of the SDK install directory below: 
 \Nordic Semiconductor
RF51 SDK_v5.1.0.36092\Nordic
rf51422\Board
rf6310adio_example
