R246 is shown in Table 10-19.

Return to the Summary Table.

Table 10-19 R246 Register Field Descriptions
Bit Field Type Reset Description
15:0 BAWFREQ_OFFSET_FIXEDLUT R/WL 0x0000

Offset value from 2467 MHz for the BAW frequency. Signed 16-bit integer value. This field is stored in the EFUSE.

Each bit of this fields corresponds to 128 ppm of frequency deviation. This field varies from part to part.

This field is for calculation purposes only, the device does not use this register for any internal calculation. Do NOT write to this field.
