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 performed.
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 145 words long, as shown below.
