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)
E - immediate value from 0 to 15, shifted left by 4 (des)
? - use this opcode entry if no parameters, else use next opcode entry
Order is important - some binary opcodes have more than one name,
