M - immediate value from 0 to 255
n - immediate value from 0 to 255 ( n = ~M ). Relocation impossible
s - immediate value from 0 to 7
P - Port address value from 0 to 63. (in, out)
p - Port address value from 0 to 31. (cbi, sbi, sbic, sbis)
K - immediate value from 0 to 63 (used in `adiw', `sbiw')
i - immediate value
l - signed pc relative offset from -64 to 63
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):
