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.
In order to compute the decimal equivalent
default value of CV29, simply write in the
rightmost column of this table the number
"2" for bit 2 and the number "4" for bit 3.
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.
