1. A short form for a relative jump to label 'KK' is the instruction
2. In the following instruction sequence, if the instruction 'LD WX, #02H' were to be executed in
3. Here is another example:
where 'KK' must be within the allowed range of current PC–15 to current PC+16. The JR
instruction has in this case the effect of an unconditional JP instruction.
place of 'LD WX,#00H', the program would jump to 1002H and 'JPS BBB' would be executed.
If 'LD EA,#04H' were to be executed, the jump would be to1004H and 'JPS CCC' would be
executed.

If 'LD EA,#01H' were to be executed in place of 'LD EA,#00H', the program would jump to
1001H and address 30H would contain the value 1H. If 'LD EA,#02H' were to be executed, the
jump would be to 1002H and address 30H would contain the value 2H.
