3.3.2 Conditional Tests
Table 3–13 lists the condition names, encodings, and tests for the conditional branch and
set instructions. The test associated with each condition is a logical formula using the current
states of the condition codes. If this formula evaluates to one, the condition is true. If the
formula evaluates to zero, 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 currently true.
