5. Sequence break instructions

Sequence breaks are jumps, branches and procedure calls and returns. In this text, we distinguish between jumps and branches, although this distinction is not made in all instruction sets:

• the jump loads the program counter with an absolute address (CP ← Address ) ;

• the branch adds a positive or negative displacement to the program counter (CP ← NCP + displacement ). The NCP value to which the displacement is added is that of the instruction following the branch.

Jumps and branches can be unconditional or conditional depending on the result of a test, which can be performed in different ways.
