1 Legend:
1 r any register
1 d 'ldi' register (r16-r31)
1 v 'movw' even register (r0, r2, ..., r28, r30)
1 a 'fmul' register (r16-r23)
1 w 'adiw' register (r24,r26,r28,r30)
1 e pointer registers (X,Y,Z)
1 b base pointer register and displacement ([YZ]+disp)
1 z Z pointer register (for [e]lpm Rd,Z[+])
1 M immediate value from 0 to 255
1 n immediate value from 0 to 255 ( n = ~M ). Relocation impossible
1 s immediate value from 0 to 7
1 P Port address value from 0 to 63. (in, out)
1 p Port address value from 0 to 31. (cbi, sbi, sbic, sbis)
1 K immediate value from 0 to 63 (used in 'adiw', 'sbiw')
1 i immediate value
1 l signed pc relative offset from -64 to 63
1 L signed pc relative offset from -2048 to 2047
1 h absolute code address (call, jmp)
1 S immediate value from 0 to 7 (S = s << 4)
1 ? use this opcode entry if no parameters, else use next opcode entry
