Description
This function registers the callback function to be called from interrupt.
Precondition
RTCC_Initialize must have been called.
Parameters
| Param | Description |
|---|---|
| callback | Function of type RTC_CALLBACK. This will be called from the interrupt service routine for RTCC. |
| context | Allows the caller to provide a context value (usually a pointer to the callers context for multi-instance clients). |
Returns
None.

void RTC_Callback( uintptr_t context)
{
// Code to be executed in the RTCC callback
}
RTCC_CallbackRegister(RTC_Callback, (uintptr_t) NULL);
Remarks
