CC3351: How Temperature Control Parameters Work

Part Number: CC3351

Hi there, 

I am from the CVTE team, and we have some questions regarding the parameters of the following commands:
1cc33xxconf -i cc33xx-conf.bin -o cc33xx-conf.bin -s core.thermal_thresholds.high_threshold_24G=0 -X
2cc33xxconf -i cc33xx-conf.bin -o cc33xx-conf.bin -s core.thermal_thresholds.high_threshold_5G=0 -X
3cc33xxconf -i cc33xx-conf.bin -o cc33xx-conf.bin -s core.thermal_thresholds.low_threshold_5G=0 -X
4cc33xxconf -i cc33xx-conf.bin -o cc33xx-conf.bin -s core.thermal_thresholds.low_threshold_24G=0 -X
Specifically, we would like to know:

1.The function of the parameters core.thermal_thresholds.high_threshold_24G, core.thermal_thresholds.high_threshold_5G, core.thermal_thresholds.low_threshold_5G, and core.thermal_thresholds.low_threshold_24G.

2.Their configurable range (minimum and maximum values).

3.Whether the values should be set in hexadecimal or decimal.

4.What is the unit of measurement for these parameters?

    Hi Yinzhe,

    As you see, there are 4 parameters for the thermal_threshold function. Two high and low thresholds for each 2.4G and 5Ghz bands.

    When the detected temperature in the cc33xx becomes higher than the high_threshold, the cc33xx thermal compensation mechanism will activate. The compensation mechanism will stay activated until the detected temperature has become lower than the low_threshold.

    I wrote is a brief psuedo code of how the feature works:

    if ((temp > core.thermal_thresholds.high_threshold_24G) && (FALSE == Isradio24GHzThermalCompensationActivated())))
    activate24GHzThermalCompensation();

if ((temp > core.thermal_thresholds.high_threshold_5G) && (FALSE == Isradio5GHzThermalCompensationActivated()))
    activate5GHzThermalCompensation();
    
if ((temp < core.thermal_thresholds.low_threshold_24G) && (TRUE == Isradio24GHzThermalCompensationActivated()))
    disable24GHzThermalCompensation();

if ((temp < core.thermal_thresholds.low_threshold_24G) &&  (TRUE == Isradio5GHzThermalCompensationActivated()))
    disable5GHzThermalCompensation();

    the firmware will translate these values as 'int16_t'. Meaning they can have range as -32,768 to 32,767.

    They can be set in either hexadecimal or decimal.

    The unit of measurement is celsius.
