rssi accuracy

Dear Dialog,

Could you tell me the actual accuracy of rssi value? Following citation is your answer to my question
about rssi resolution. This explains the resolution is 0.474dBm within the range of -90dBm to -20dBm.
What I'd like to know is the maximum error of rssi is 1LSB? 2LSB? or more? I'm using DA14580.

Best Regards,

> The base value is -112.0 dBm, this is the indicated RSSI when the input signal is 0, no RF signal present.
> The RSSI value that is read from the register indicates the number of RSSI steps above this -112 dBm.
>步骤约为0.474 dB / LSB。的响了e is FF = 255 steps and the max value is -112 + (255 * 0.474) =
> +8.8 dBm. The usable range though is from -90dBm to -20 dBm due to the limited linear range.
