TB: First comparison table word
TB is the first word of the comparison table. The structure of the
comparison table depends on the type of comparison being per-
formed.
• For target value comparison, the length of the comparison table
is determined by the number of target values specified in TB.
The table can be between 4 and 19 words long, as shown
below.
