Note
Invalid [Enable online edit when Scan Replay/Step Run] makes impossible to
use the Scan Replay function. Also, online editing during Step Run auto-
matically enters PROGRAM mode. (When valid, Scan Replay will automati-
cally be performed.) Invalid [Enable online edit when Scan Replay/Step Run]
improves the process speed of one scan than when valid. This setting is ef-
fective when debugging a large-scale program with the virtual external input.
