No changes, just resending.

I can add a note, how about:
After clearing the pre-existing UA(s) the Target shall set initial UA
condition(s)
a) to its power-on value.
or
b) to "Power On" UA.

Also, a sentence in 10.5 states:
"A "Y" in the corresponding column indicates the object is cleared to its
default
or power-on value within the device upon completion of specified action."

  No changes, just resending. A comment on the table itself. 
The row for 'Pre-existing ACA, UA, and Deferred error conditions 
cleared' is correct, however I believe some additional words (perhaps in 
a note) would help clarify things.  The exact same actions which "clear" 
the ACA, UA, and deferred error also cause the normal, "start of day" 
type unit attentions to be established.  The chief example is Power Up 
unit attention (29/00).  I assume this was not part of the table in PLDA 
because the table is "clearing effects".  However, we have seen 
integration problems relating to this and I think a note associated with 
this column would be helpful. Comments? I can add a note, how about: 
After clearing the pre-existing UA(s) the Target shall set initial UA condition(s) 
a) to its power-on value. 
or 
b) to "Power On" UA.
