 ### `Z80` emulator instance
 
 This structure contains the state of the emulated CPU and callback pointers necessary to interconnect the emulator with external logic. There is no constructor function, so, before using an object of this type, some of its members must be initialized, in particular the following: `context`, `read`, `write`, `in`, `out`, `int_data` and `halt`.

 **Details**  
 The value of the R register is incremented as instructions are executed, but its most significant bit remains unchanged. For optimization reasons, this bit is saved at the beginning of the execution of `z80_run` and restored before returning. If an instruction directly affects the R register, this variable is also updated accordingly.

 **Details**  
 Since instructions with prefix `DDh` and `FDh` behave similarly, differing only in the use of register IX or IY, for reasons of size optimization, a single register is used that acts as both. During opcode analysis, the IX or IY register is copied to this variable and, once the instruction emulation is complete, its contents are copied back to the appropriate register.
