MC9S08QG8 Stop Mode 2, Exit with RTI -> How?

[chumpykid]

Being new to this processor, I'm having trouble finding the correct way to enter/exit Stop Mode 2 from RTI.  Enter stop mode in main, then somehow exit in the RTI.  Below is minimal code to use to show an example....  I've enabled stop2 in SPMSC2= 0x03 and STOPE in SOPT1.  Any help would be appreciated.

void main(void)
{

   // Initialization
   MCU_init();

   // Enable Interrupts
   EnableInterrupts;

   // Background Loop
   while (1)
   {
           // Feed the dog
           __RESET_WATCHDOG();
       
           // check inputs
           CheckInputs(); 

           // Put into Stop Mode
           asm stop;    
   }
}

// RTI interrupt for Real Time Clock
void interrupt 23 RTI_Isr (void)
{

   // Acknowledges RTI Flag
   SRTISC_RTIACK = 1; 

   // Exit Stop Mode 2 here?

   // Time Keeping here

}

After some painful tech support...  I can almost answer my own question..

Apparently if you have an "asm stop" in a while loop, it doesn't even bother to do the RTI.  If in stop mode 1 or stop mode 2, it does a POR, so you do not need to keep this in a loop, although the syntax is correct.

Stop Mode 3, I have yet to get it working correctly.  Stop Mode 3 does not do the POR, so you must keep it in some sort of loop.  I do see an overall drop in current, but not the results I would expect.
