RTOS/CC1310EMK: TX power setting of high speed mode in CC1310

Part Number:CC1310EMK

Tool/software:TI-RTOS

Hello TI employees, 

I'd like to know the TX power of CC1310 HSM example, i.e. rfPacketErrorRate. 

Thanks a lot if anyone could help me. 

It shows as following in smarrf_settings_predefined.c: 

// CMD_RADIO_SETUP HSM
rfc_CMD_RADIO_SETUP_t RF_cmdRadioSetup_hsm =
{
.commandNo = CMD_RADIO_SETUP,
.status = 0x0000,
.pNextOp = 0x00000000,
.startTime = 0x00000000,
.startTrigger.triggerType = 0x0,
.startTrigger.bEnaCmd = 0x0,
.startTrigger.triggerNo = 0x0,
.startTrigger.pastTrig = 0x0,
.condition.rule = 0x1,
.condition.nSkip = 0x0,
.mode = 0x05,
.loDivider = 5,
.config.frontEndMode = 0x0,
.config.biasMode = 0x1,
.config.bNoFsPowerUp = 0,
.txPower = 0x23F,
.pRegOverride = pOverrides_hsm,
};

So the txPower parameter is set to 0x23F. Am I right?

If it is, what is the exact dBm corresponding to 0x23F?

How to set txPower to be, say, 13dBm?

Thank you in advance.
