Reference
Zilog Z80
140 mnemonics, 796 encoded forms, operands little-endian. Generated from crates/isa/src/z80.rs.
100 of those forms are undocumented opcodes, marked undocumented below. They encode, because real programs use them.
Cycle counts show the base cost; +p is an extra cycle when an
indexed access crosses a page boundary, +t when a branch is taken.
