Timing

Tell me what is the duration in bars
of the JR NN command, but in general it would be good to know
where you can find such information, for example on the Internet.

Sincerely

For conditional (CALL,JR,...) and cyclic commands (DJNZ,LDIR,...) two
time values are given. The larger value is when a condition is met or when a
loop is executed.
The values in parentheses refer to the longer way of encoding some
commands.

Warm regards, Glory!

Greetings, dear Vyacheslav!

Monday June 16, 1997 16:22, Vyacheslav Mednonogov spoke to Vladimir

And there are also commands:

Commands with the prefix DD CB or FD CB 23
Prefix DD or FD 4

Regards &y \PoS\PCCC

PS. And the rest seems to be correct, it has never let me down!
(by the way, I also received data on undocumented commands with his help)
