as implements all the standard AVR opcodes.
The following table summarizes the AVR opcodes, and their arguments.
Legend:
r any register
d `ldi' register (r16-r31)
v `movw' even register (r0, r2, ..., r28, r30)
a `fmul' register (r16-r23)
w `adiw' register (r24,r26,r28,r30)
e pointer registers (X,Y,Z)
b base pointer register and displacement ([YZ]+disp)
z Z pointer register (for [e]lpm Rd,Z[+])
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
