Description
Frame
Displays trace frame numbers.
Valid range: 0 < Trace frame number < 32,767
Displays the number of clock pulses taken by the target chip between the start of

Instead, the 10-MHz clock signal of the in-circuit emulator is used.
Measurement range: 1 < Time tag < 0xffffff

IF :
Invalid fetch
Displays data access results. This field displays the following information
depending on the access status display in the Status field:
