, Conditional Jump
[AK7712A-VT]
The conditional jump is shown in the figure below. By this command, condition flag(SGF, OVF, ZRF of ALU) is
judged before jump, and if it is satisfied then the address of jump destination is set. Then 1 machine cycle of NOP is
inserted similar to jump. And if it is not satisfied then NOP is not inserted, and next address command is executed.
The list of conditional jump is shown below.
