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.

This is because there's bitwise ORing involved in the creation
of the final opcode, which makes z80a's approach impractical.
This makes labelling a bit different too. Instead of expecting
label words after the naked branching op, we rather have label
words expecting branching wordref as an argument. Examples:
L2 ' BRTS FLBL! ( branch forward to L2 )
L1 ' RJMP LBL, ( branch backward to L1 )

This program allows you to access AVR chips Flash memory, EEPROM
and fuses using a SPI relay. This requires drivers that imple-
