Thus, Dx now contains the following bit pattern:
Using this information, the table instruction calculates dependent variable Y:
The function chosen for Examples 1 and 2 is linear between data points. If another function
had been used, interpolated values might not have been identical.
5.3.4.3 TABLE EXAMPLE 3: 8-BIT INDEPENDENT VARIABLE. This
how to use a table instruction within an interpolation subroutine. Independent variable X is
calculated as an 8-bit value, allowing 16 levels of interpolation on a 17-entry table. X is
passed to the subroutine, which returns an 8-bit result. The subroutine uses the data listed
in Table 5-15, based on the function shown in Figure 5-9.
