8.1.11 Trace Information
Selecting [View -> Code -> Trace] or clicking the [Trace] toolbar button displays the [Trace] window. Trace
information that can be acquired by the emulator and trace information items to be displayed are as listed below.
[PTR] Cycle number in the trace buffer. When the most recent record is record 0,
earlier record numbers go backwards (-1, -2, ...). If a delay count has been
set, the cycle number where the trace stop condition has been satisfied is
record 0. For the cycle (during delay) executed until the trace has stopped,
earlier record numbers go forward (+1, +2, ...) the most recent record.
[Address] Address (6-digit hexadecimal)
[Instruction] Disassembled code of the executed instruction
[Data] Data bus value, displayed as 2-digit or 4-digit hexadecimal
[R/W] Whether access was read (RD) or write (WR)
[Area] Memory area being accessed; ROM, RAM, or 8- or 16-bit I/O (not available
when a time stamp is acquired)
[Status] Bus status during this cycle; PROG (prefetch) or Data (CPU data access
cycle) (not available when a time stamp is acquired)
[Mode] Operating mode; ACT (active) or SUB (subactive) (not available when a
time stamp is acquired)
[Probes] A 4-bit binary number showing the four probe pins in the order of Probe 4,
Probe 3, Probe 2, and Probe 1 from the left (not available when a time
stamp is acquired).
[NMI] Status of the NMI input (not available when a time stamp is acquired)
[Timestamp] Time stamp of the record. Time stamps start from zero each time the user
program is executed. The timer resolution depends on the time stamp
clock rate selected in the trace acquisition (only available when a time
stamp is acquired).
[Source] Source program
[Label] Label information that corresponds to the address (if defined)
[Timestamp-
