5.3.3.10 CONDITION TESTS. Conditional program control instructions and the TRAPcc
instruction execute on the basis of condition tests. A condition test is the evaluation of a
logical expression related to the state of the CCR bits. If the result is 1, the condition is
true. If the result is 0, the condition is false. For example, the T condition is always true,
and the EQ condition is true only if the Z-bit condition code is true. Table 5-12 lists each
condition test.
5.3.4 Using the TBL Instructions
There are four TBL instructions. TBLS returns a signed, rounded byte, word, or long-word
result. TBLSN returns a signed, unrounded byte, word, or long-word result. TBLU returns
an unsigned, rounded byte, word, or long-word result. TBLUN returns an unsigned,
unrounded byte, word, or long-word result. All four instructions support two types of
interpolation data: an n-element table stored in memory and a two-element range stored in
a pair of data registers. The latter form provides a means of performing surface (3D)
interpolation between two previously calculated linear interpolations.
The following examples show how to compress tables and use fewer interpolation levels
between table entries. Example 1 (see Figure 5-7) demonstrates TBL for a 257-entry
table, allowing up to 256 interpolation levels between entries. Example 2 (see Figure 5-8)
reduces table length for the same data to four entries. Example 3 (see Figure 5-9)
demonstrates use of an 8-bit independent variable with an instruction.
