RTC Alarm does not work properly.

Hi,

In MQX4.0.1, I use the following code to create a RTC alarm. But when it enter the rtc_alarm_interrupt, the RTC_SR is always 0x10 which seems wrong. Because it is an alarm interrupt, it should be 0x04. Please advice.

Thank you.

void rtc_alarm_interrupt(pointer rtc_registers_ptr)

{

uint_32 ui32Status = 0;

ui32State = _rtc_get_status();

if(ui32State & RTC_RTCISR_ALM)

{

}

ui32Status = RTC_SR;

_rtc_clear_requests(ui32State);

}

void main()

{

DATE_STRUCT alarm_time_rtc;

TIME_STRUCT alarm_time_mqx;

if(MQX_OK != _rtc_int_install(rtc_alarm_interrupt))

{

_task_block();;

}

_rtc_clear_requests(RTC_RTCISR_ALM);

if(0 == _rtc_int_enable(TRUE, RTC_RTCIENR_ALM))

{

_task_block();

}

_rtc_set_alarm_mqxd(&alarm_time_rtc);

_time_to_date(&alarm_time_mqx, &alarm_time_rtc);

alarm_time_rtc.SECOND += 30;

for(;;);

}
