1.25.22.12 PMECC_CallbackRegister Function
C
void PMECC_CallbackRegister( PMECC_CALLBACK callback, uintptr_t context )
Summary
Sets the pointer to the function (and it's context) to be called when the given PMECC's interrupt occurred.
Description
This function sets the pointer to a client function to be called "back" when the given PMECC's interrupt occurred. It also passes a context value (usually a pointer to a context structure) that is passed into the function when it is called. This function is available only in interrupt mode of operation.
Precondition
PMECC_Initialize must have been called for the associated PMECC instance.
Parameters
| Param | Description |
|---|---|
| callback | A pointer to a function with a calling signature defined by thePMECC_CALLBACK data type |
| context | A value (usually a pointer) passed (unused) into the functionidentified by the callback parameter |
Returns
None.
Example
void pmeccCallback( uintptr_t context, uint32_t interruptStatus )
{
}
PMECC_CallbackRegister(pmeccCallback, (uintptr_t)NULL);
Remarks
The context parameter is ignored if the pointer passed is NULL. To disable the callback function, pass a NULL for the callback parameter. See the PMECC_CALLBACK type definition for additional information.
