Table Example 2: Compressed Table - Motorola CPU32 Reference Manual

The table instruction is executed with the following bit pattern in Dx:
31
NOT USED
Table Entry Offset → Dx [8:15] = $A3 = 163
Interpolation Fraction → Dx [0:7] = $80 = 128
Using this information, the table instruction calculates dependent variable Y:
Y = 1669 + (128 (1679 – 1669)) / 256 = 1674
