The Assembler is not case sensitive.

The operands have the following forms:

Rd: R0-R31 or R16-R31 (depending on instruction) Rr: R0-R31

b: Constant (0-7) s: Constant (0-7)

P: Constant (0-31/63)

K: Constant (0-255)

k: Constant, value range depending on instruction. q: Constant (0-63)

Rdl: R24, R26, R28, R30. For ADIW and SBIW instructions
