Operation
If cc (condition code) is true, then PC â dst
A conditional jump transfers Program Control to the destination address
if the condition speciï¬ed by cc (condition code) is true. Otherwise, the
instruction following the JP instruction is executed. See Section 12.3 for a
list of condition codes.
The unconditional jump simply replaces the contents of the Program
Counter with the contents of the register pair speciï¬ed by the destination
operand. Program Control then passes to the instruction addressed by the
PC.
