P - Port address value from 0 to 63. (in, out)
p - Port address value from 0 to 31. (cbi, sbi, sbic, sbis)

L - signed pc relative offset from -2048 to 2047
h - absolute code address (call, jmp)
S - immediate value from 0 to 7 (S = s << 4)
? - use this opcode entry if no parameters, else use next opcode entry
Order is important - some binary opcodes have more than one name,
the disassembler will only see the first match.

as normal instructions if not all of the bits are decoded):
