{L/S}DJNZLC[n],src DecrementCounter,{Long/Short}JumpNotZero
Description: The DJNZ LC[n], src instruction performs a conditional branch based upon the associated Loop
Counter (LC[n]) reg- ister . The DJNZ LC[n], src instruction decrements the LC[n] loop counter
and branches to the address defined by src if the decremented counter has not reached 0000h .
Program branches can be relative or absolute depending upon the src specifier and may be quali-
fied by using the ‘L’ or ‘S’ prefixes as documented in the JUMP src op code .
StatusFlags: None
Operation: LC[n] ← LC[n] -1
LC[n] <> 0: IP ← IP + src (relative) -or- src (absolute)
LC[n] = 0: IP ← IP + 1
