{L/S}JUMP C/{L/S}JUMP NC, src, Conditional {Long/Short} Jump on Status Flag

L/S}JUMP Z/{L/S}JUMP NZ, src,

{{L/S}JUMP E/{L/S}JUMP NE, src,

{L/S}JUMP S, src

Description: Performs conditional branching based upon the state of a specific processor status flag. JUMP C

results in a branch if the Carry flag is set while JUMP NC branches if the Carry flag is clear. JUMP

Z results in a branch if the Zero flag is set while JUMP NZ branches if the Zero flag is clear. JUMP E

results in a branch if the Equal flag is set while JUMP NE branches if the Equal flag is clear. JUMP S

results in a branch if the Sign flag is set. Program branches can be relative or absolute depending

upon the src specifier and may be qualified by using the ‘L’ or ‘S’ prefixes as docu- mented in the

JUMP src op code. Special src restrictions apply to JUMP E and JUMP NE.

Status Flags: None

JUMP C C=1: IP ← IP + src (relative) -or- src (absolute)

Operation:

C=0: IP ← IP + 1
