OOPS!
    I was aware of using the RC osc to clk the A/D.  But the A/D is
not listed as a peripheral that can wake up the processor from sleep
mode on my spec. sheet (section 14.8).  I regurgiated this fact in a previous
message.  However, in the A/D section it does state a A/D interrupt
can wake up the processor from sleep mode.
