Table 12.
Relative offset
The destination address for these jumps is specified to the assembler by a label or by an
actual address in Program memory. However, the destination address assembles to a
relative offset byte. This is a signed (two’s complement) offset byte which is added to the PC
in two’s complement arithmetic if the jump is executed.
The range of the jump is therefore -128 to +127 Program Memory bytes relative to the first
byte following the instruction.
Jump instructions
Table 13
instruction, but in fact there are three SJMP, LJMP, and AJMP, which differ in the format of
the destination address. JMP is a generic mnemonic which can be used if the programmer
does not care which way the jump is en-coded.
The SJMP instruction encodes the destination address as a relative offset, as described
above. The instruction is 2 bytes long, consisting of the opcode and the relative offset byte.
The jump distance is limited to a range of -128 to +127 bytes relative to the instruction
following the SJMP.
