5.19 Branch Instructions

Branch instructions cause a sequence to change when specific conditions

exist. The CPU12 uses three kinds of branch instructions. These are short

branches, long branches, and bit condition branches.

Branch instructions can also be classified by the type of condition that must

be satisfied in order for a branch to be taken. Some instructions belong to

more than one classification. For example:

• Unary branch instructions always execute.

• Simple branches are taken when a specific bit in the condition code

• Unsigned branches are taken when comparison or test of unsigned

quantities results in a specific combination of condition code register

bits.

• Signed branches are taken when comparison or test of signed

quantities results in a specific combination of condition code register

bits.
