CC1310: How can I use the Freq of 718-800MHz in HSM(high speed mode, 4MHz datarate)

Part Number:CC1310

Reference the example of "rfPacketErrorRate_CC1310_LAUNCHXL_nortos_ccs", my CC1310 project can communication by the Freq of 868 or 915MHz in HSM(high speed mode, 4MHz datarate). 

Now I want to know how to use cc1310 communication  by  the Freq of 718-800MHz in HSM(high speed mode, 4MHz datarate).Tks!
