21 | The Zilog Z80 is an 8-bit microprocessor compatible with the Intel 8080. | |
22 | ||
23 | In addition to the 8-bit data bus, this decoder requires the input signals | |
24 | /M1 (machine cycle), /RD (read) and /WR (write) to do its work. An explicit | |
25 | clock signal is not required. However, the Z80 CPU clock may be used as | |
26 | sampling clock, if applicable. | |
27 | ||
28 | Notes on the Z80 opcode format and descriptions of both documented and | |
29 | "undocumented" opcodes are available here: | |
