---

This function sets the flag which indicates if a new sample(s) is available for reading.

Parameters

[in]

pUserData

This is a void pointer to the instance of the user specific data structure for the ISR.

Returns

void There is no return value.

Constraints:

None

Yes

Set flag to indicate Sensor has signaled event ready.
