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, 8- or 16-bit I/O, 8- or 16-bit EXT

(external), or DTC RAM (not available when a time stamp is acquired)

[Status] Bus status during this cycle; DTC operation, PROG (prefetch), Data (CPU

data access cycle), Refresh (refresh cycle), or DMAC (DMAC cycle) (not

available when a time stamp is acquired)

[Clock] Number of clock cycles in bus cycle as 1 to 8. To indicate more clock

cycles, “OVR” is displayed (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)

[IRQ5-0] Status of six IRQ inputs (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)

1 2 ... 387 388 389 390 391 392 393 394 395 396 397 ... 429 430
