R/W Description
7:0 FREQOFF_EST
R
The estimated frequency offset (2’s complement) of the carrier.
Resolution is FXTAL/2¹⁴ (1.59 - 1.65 kHz); range is ±202 kHz to
±210 kHz, dependent of XTAL frequency.
Frequency offset compensation is only supported for 2-FSK;
GFSK and MSK modulation. This register will read 0 when
using OOK modulation.
