Unless otherwise noted in the flags, these opcodes support these 4 forms :
* short register (RR)
* short immediate (4-bit iR)
* Long immediate (16-bit IRR)
* Extended register (RRR) with conditional (RRRRc) and increment features.
Look at instructions.html for a detailed description of the instruction word's structure.
The instruction's "form" reflects the semantics of the instruction. It is the assembler's view of the encoding.
The flags contain the informations used by the assembler to transform the semantic into an encoded binary word.
