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.
