Table A-8. Instruction Lengths and Hexadecimal Opcodes (Continued)
NOTES:
1. For indexed instructions, the first column lists instruction lengths as
S
/
L
, where
S
is the short-indexed
instruction length and
L
is the long-indexed instruction length.
2. For the SCALL and SJMP instructions, the three least-significant bits of the opcode are concatenated
with the eight bits to form an 11-bit, two’s complement offset.
