What are the trim value override registers and when should they be used?

[CurtisHx]

On the nRF51, there are 5 OVERRIDE registers (0-4) in the radio module.

What do those registers do and when should they be used? The FRM was not clear about them.

Hi,

Please see this answer. Note that the SoftDevice will handle this for you automatically.

Best regards,

If you are implementing your own proprietary BLE stack, then yes. Otherwise you should be fine with leaving them as is.
