WAKE up pin

Other Parts Discussed in Thread: TMS320C5515

Can someone help please.

I need to set Wake up pin low till the alarm. After Alarm it will be High.

The problem is : When i call function where i set  Wu_dout bit  Low in RTCPMGT register it`s ok it becomes low

but right after i escape from fuction it is again High. I need it to stay Low till next alarm.

Dunno what to do.

 

void Wake_low ()
{
       
         
    *(ioport volatile unsigned *)0x1930 = 0x0009;
         
      
    
     printf ("Wake Lowy\n");
     Flag++;
     AlarmUpdate ();
    
}
