pStrTemperature = pObjTempSensor->GetTemperature (pObjTempSensor,

TS_TRUE);

TempSensor:: SetTempHysteresis API function

Table 16 describes the SetTempHysteresis function of the TempSensor structure.

Example:

TS_TemperatureType strTestTemperature;

...

/* Write the following value for Hysteresis register: +75.5° C

strTestTemperature.TS_Sign

= TS_PLUS_SIGN;

strTestTemperature.TS_IntegerValue = 75;

strTestTemperature.TS_DecimalValue = 5;

/* 0 or 5 only */

pObjTempSensor->SetTempHysteresis (pObjTempSensor,

&strTestTemperature);

TempSensor:: GetTempHysteresis API function

Table 17 describes the GetTempHysteresis function of the TempSensor structure.
