6.3.2. Configuration of RF InitConfig Parameters
RF InitConfig parameters are listed in the lower part of Figure 6-2. The description of
parameters’ configuration is shown in Table 6-4.
TOUT PinConf
Configure the TOUT pin according to the actual TOUT pin status. We recommend
the default value.
• TOUT_ADC_EN: When the TOUT pin connects to an external circuit,
measure the external voltage (0V - 1V) through the internal ADC.
• TOUT_VDD_EN: When TOUT pin is left floating, measure VDD33 voltage
through uint16 system_get_vdd33(void).
⚠ Notice:
• Users cannot configure TOUT_ADC_EN and TOUT_VDD_EN at the same
time.
•
When users use TOUT_ADC_EN, they need to input the actual voltage on
VDD3P3 pin 3 and pin 4.
FreqOffset
• SetFreqEnable: Set the frequency offset manually.
-
PracticalFreqOffset: the option is valid when selecting SetFreqEnable.
• AutoCalEn: Set the frequency offset automatically.
RFInt mode
Users can select the RF initialization mode:
• LoadRFCalParam: During the RF initialization, RF data are loaded directly
from the flash without any calibration. It takes about 2 ms and the least initial
current.
• TxPwrCtrl in init: During the RF initialization, only Tx Power calibration will
be performed, and other data are loaded from flash. It takes about 20 ms
and small initial current.
• FullRFCal in RFInit: All calibrations are performed during the RF
initialization. It takes 200 ms and large initial current.
