The location where the core will execute the next instruction is pointed to by the destination register (in SRC2). Prepare it in advance !
Because it is unconditional, the SRC1 field is ignored, as well as the optional Imm16 field.
The other instructions of the JMP group are conditional, see also : JZ/JNZ, JO/JNE/JNO/JE, JS/JNS
