Hi, Arpad;

 

You are right there is no statement in the BIRD about "if
GetWave_Exists=False, Use_Init_Output must be True". But it's the same
as "Use_Init_Output is False, GetWave_Exists must be True".

Fangyi,

 

Thanks for your comments.

 

I did find on pg. 145 that "If Use_Init_Output is False, GetWave_Exists
must be True.",

but I can't find what you are saying: " if GetWave_Exists=False,
Use_Init_Output must be True."

Could you give me a page number for that?

 

Thanks,

 

Arpad

Hi, Arpad;

 

I think your second table is also correct. I just want to point out that
the current BIRD explicitly states that if GetWave_Exists=False,
Use_Init_Output must be True. Although it won't change the logic of the
table, those X's for Use_Init_Output when GetWave_Exists=False should be
replaced by True.

Fangyi

Dear AMI experts, 
  
I cleaned up the spreadsheet with the truth table that we discussed 
in our ATM meeting today.  It looks like this now: 

 

I hope I got it right this time. 

The next thing I would like to do is to extend this table 
and spell out how these conditions can be applied to Tx 
and Rx independently.  In other words, I don't believe 
that our intent was to require these Booleans to be the 
same for both Tx and Rx.  But how many combinations are 
valid? 

We have four (4) combinations per buffer, and we have two 
buffers, which could theoretically allow 4^2 = 16 total 
possibilities.  Are they all valid? 

 

Thanks, 

Arpad
