The first column is the value passed to the subroutine, the second column is the value
expected by the table instruction, and the third column is the result returned by the subrou-
tine.
The following value has been calculated for independent variable X:
Since X is an 8-bit value, the upper four bits are used as a table offset, and the lower four
bits are used as an interpolation fraction. The following results are obtained from the sub-
routine:
Thus, Y is calculated as follows:
Y = 80
If the 8-bit value for X were used directly by the table instruction, interpolation would be in-
correctly performed between entries 0 and 1. Data must be shifted to the left four places be-
fore use:
