3.7.7.9 RF Calibration
The temperature-dependent drift of the XTAL-based RF can be optionally corrected for each service/channel configuration. To enable the RF calibration for the selected service/channel configuration, set the RF_CAL bit in the eepTrxConf.sysStartConfig EEPROM setting to start RXMode immediately after power-on, or activate it in the systemModeConfig parameter when using the Set System Mode SPI command.
| Address | Name | Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 |
|---|---|---|---|---|---|---|---|---|---|
| 0x0019 | sysStartConfig | RF_CAL | — | VCO_TUNE | IDLEModeSelector | — | TMDEN | OPM[1:0] | |
| systemModeConfig | RF_CAL | — | VCO_TUNE | IDLEModeSelector | — | TMDEN | OPM[1:0] | ||
RF calibration requires additional time. See Tune and Check from Related Links.
