Thanks again Jerson. From everything I have read I thought the clearing of the mismatch and the clearing of the interrupt must occur before the RESUME statement at the end of an interrupt service routine?? Your suggestion to put them in the MAIN loop before the SLEEP statement is something I had not heard. I will try it to see.
I did find part of the problem. I commented out the @ NOP statement after the @ SLEEP statement and now the power consumption is as follows:
1) On Power up in the MAIN loop: 400 uamps
2) During ops after Interrupt in Int_Handler: 4 mamps
3) After completion of Int_Handlr (not sure whether program is at the SLEEP statement in the MAIN loop or not): drops back to 1.74 mamps.
But it is obviously not back into deep sleep since it didn't go to 400 uamps after the Int_Handlr.
4) If I remove power and then reapply power it goes to 400 umaps again.

Any other ideas on why it apparently isn't going into deep sleep after the Int_Handlr??
