- This assembler works very much like Z80 assembler (B200) so
- refer to this documentation first. Here, we document specifici-
- ties.
-
- All mnemonics in AVR have a single signature. Therefore, we
- don't need any "argtype" suffixes.
-
- Registers are referred to with consts R0-R31. There is
- X, Y, Z, X+, Y+, Z+, X-, Y-, Z- for appropriate ops (LD, ST).
- XL, XH, YL, YH, ZL, ZH are simple aliases to R26-R31.
-
- Branching works differently. Instead of expecting a byte to be
- written after the naked op, branching words expect a displace-
- ment argument.
