From the definition of CV29 given in Table 
1, we see that the default values of bits 1 
and 2 are binary 1s; whereas, all other bits 
in CV29 have a default value of binary 0. 
To compute the decimal equivalent default 
value of CV29, simply write in the 
rightmost column of this table the number 
"2" for bit 1 and the number "4" for bit 2. 
Then add up all the non-zero numbers that 
you have entered into this rightmost 
column. Since the sum of these numbers 
is 6, the decimal number to be 
programmed into CV29 is 6. 
7  128   
SUM:  6
