C
void RTC_Timer32CallbackRegister ( RTC_TIMER32_CALLBACK callback, uintptr_t context )
Summary
Register the callback function to be called when an 32-bit Timer Interrupt occurs.
Description
This function registers the callback function that the library will call when an interrupt occurs. The library will return the event that has caused the interrupt and the application specified context in the callback function.
Precondition
The RTC_Initialize() function should have been called to initialize the RTC module. The module should have been configured for 32-bit Timer Counter operation in MHC. The library should have been configured for Interrupt mode operation.
Parameters
| Param | Description |
|---|---|
| callback | A pointer to a function with a calling signature defined by the RTC_TIMER32_CALLBACK data type. Passing a NULL value disables the callback |
| context | A value (usually a pointer) that passed into the callback function when the callback function is called |
Returns
None.
Example
// Refer to the description of the RTC_TIMER32_CALLBACK datatype for // example usage of this function.
Remarks
