RTCResult RTC_SetAlarmStatusAsync(
RTCAlarmChan chan,
const RTCAlarmStatus* status,
RTCCallback callback,
void* arg );
chan |
Uses RTCAlarmChan to specify the alarm channel. |
status |
Pointer to RTCAlarmStatus containing status to set. |
callback |
Pointer to the callback function. This callback is called from within the interrupt handler. |
arg |
Argument to pass to the callback function. |
If the request succeeds, it returns 0. If the request fails, it returns some numeric value other than 0.
This function asynchronously writes alarm permission status for the real time clock. It sends a request to ARM7 to allow alarm permissions and returns the process result without waiting for a response from the processor. To get the result from the processor, you must use the result
argument. If this function fails, no operation is performed and no user callback function is called.
In write alarm state, do not set to any state other than enable or prohibit. Values are written to the variable specified by the status
argument asynchronously. Do not use this variable for anything else until a user callback function confirms the completion of this operation.
