(1):frame number (Decimal number)

(2):executed instruction address, and data access address (Hexadecimal number)

(3):data (Hexadecimal number)

(4):access information (a-status)

IWA

:

write access to internal memory

EWA

:

IRA

:

read access to internal memory

ERA

:

read access to external memory

ICF

:

code fetch to internal memory

ECF

:

---

:

valid "d-status" information

(5):device status (d-status)

STANDBY

RESET

-------

:

(6):instruction queue status

FLH

:

flush queue

-by

:

number of remainder code of queue is - byte (-: 1 to 8)

(7):information valid flag

&

:

address is valid

@

:

data is valid

(8):event information

C

:

code event

D

:

data event

(9):time stamp display (ns unit)

displays difference of executed time between this frame and next frame (decimal)

Note:

Information about event hits is excluded from the displayed information. For code execution, in
particular, the effect of a prefetch is eliminated in consideration of the count of data in the instruction
queue. Therefore, the information about hits is displayed for frames after a prefetch frame at an
address for which an event is set.
