3.4.6.27 JL

JL Jump if less

Syntax JL label

Operation If (N .XOR. V) = 1 then jump to label: PC + 2 offset → PC

If (N .XOR. V) = 0 then execute following instruction

Description The status register negative bit (N) and overflow bit (V) are tested. If only one is set, the

10-bit signed offset contained in the instruction LSBs is added to the program counter. If

both N and V are set or reset, the instruction following the jump is executed.

This allows comparison of signed integers.

Status Bits Status bits are not affected.

Example When the content of R6 is less than the memory pointed to by R7, the program

continues at label EDE.

CMP @R7,R6 ; R6 < (R7)?, compare on signed numbers

JL EDE ; Yes, R6 < (R7)

...... ; No, proceed
