#include <nitro/rtc.h>RTCResult RTC_GetAlarmStatusAsync(
RTCAlarmChan chan,
RTCAlarmStatus* status );
RTCCallback callback,
void* arg );
This function asynchronously reads alarm interrupt permission status from the real-time clock. It queries ARM7 for the values of the alarm permission status and returns the results without waiting for a response from the processor.
Values are written to the variable specified by the status argument asynchronously with respect to the function. Do not use this variable for anything else until a user callback function confirms the completion of this asynchronous operation.
