TempSensor:: SetRegister API function

Table 11 describes the SetRegister function of the TempSensor structure.

This function can be considered as an advanced function for the final user who knows

STLM75 internal registers. This function call can be avoided by calling one of the following

specific functions:

SetConfiguration, SetTempHysteresis, SetTempOverLimit;

Note that calling the SetRegister advanced function instead of a specific one, internal

TempSensor object data (m_Configuration, m_TempHysteresis, m_TempOverLimit) is not

assigned.

Required preconditions

NewTempSensorObj function must have been called before.

Called functions

None

Function name

SetRegister

Function prototype

TS_ErrStatus SetRegister (TempSensorType* pThis,

TS_RegSelectionType eRegSelection, TS_u16 uRegValue)

Behavior description

Set the STLM75 register identified by eRegSelection type with the value

passed as parameter

Input parameter {x}

pThis - Object pointer;

eRegSelection - The type associated to the register to be set;

uRegValue

- The value to be assigned to the register. This is a 16-bit

value, so for the 8-bit register, only the LSB must be considered

Output parameter {x}

None

Return value

TS_OK if successful, TS_ERROR otherwise

Required preconditions

NewTempSensorObj, TempSensor:: Init functions must have been called

before.

Called functions

HAL function:

TS_ErrStatus TS_SetPointerRegister(…);

TS_ErrStatus TS_FillRegisterFromData(…);
