BLE4.0 TX frequency

[wiki]

Hello NORDIC

We found that TX frequency error is quite large. Is it able to compensate TX frequency by software ?

Are you running a softdevice? Those registers are part of the RADIO module so you can't access them. So they're no use to you and you have to fix the crystal oscillator. Have you read the Crystal Oscillator White Paper which explain this?
