8.1.10 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; internal ROM, internal RAM, I/O, or LCDRAM
(not available when a time stamp is acquired)
[Status] Bus status during this cycle; CPU (CPU data access cycle), CPU_PREFETCH
(prefetch), SUB_ACTIVE_DATA (sub-active data access cycle),
SUB_ACTIVE_PREFETCH (sub-active prefetch), CPU_MEDIUM_DATA
(medium-speed data access cycle), or CPU_MEDIUM_PREFETCH (medium-
speed prefetch) (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).
[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 for the address (if defined)
[Timestamp-
Difference]
Difference from the timestamp value shown on the previous line (only available
when a time stamp is acquired)
