SJMP rel
Function:
Short jump
Description:
Program control branches unconditionally to the specified address. The branch destination is computed by adding the
signed displacement in the second instruction byte to the PC, after incrementing the PC twice. Therefore, the range
of destinations allowed is from 128 bytes preceding this instruction to 127 bytes following it.
Example :
The label ”RELADR” is assigned to an instruction at program memory location 0123h. The instruction SJMP
RELADR assembles into location 0100h. After executing the instruction, the PC contains 0123h.
Note :
In the above example, the instruction following SJMP is located at 102h. Therefore, the displacement byte of the instruction is the relative offset
(0123h-0102h) = 21h. Put another way, an SJMP with a displacement of 0FEh would be a one–instruction infinite loop.
