The following conventions are used:

  1. HHLL indicates a 16 bit word
  2. NN indicates an 8 bit byte

Each instruction is given with the prefix byte(s), opcode and parameters, along with the assembly language representation.

The Z80 stores words in a little-endian format; that is the least significant byte is stored first. For example:

-- -- 01 23BF  : LD BC,&BF23
