Shows trace cycles. Double-click here to bring up a dialog
box to change the displayed cycle.
Shows labels corresponding to address bus information.
Double-click here to bring up a dialog box to search for
addresses.
Shows the status of the address bus.
Shows the status of the data bus.
Shows the width of the external data bus. “16b” for 16 bits
wide bus and “8b” for 8 bits wide bus are displayed.
Shows the status (0 or 1) of the BHE (Byte High Enable)
signal. If this signal = 0, the odd-address data is valid.
Shows the status between the BIU (Bus Interface Unit) and
memory or I/O.

Shows the status of the data bus.
Displayed as “R” for Read, “W” for Write, and “–” for no
access.
This is the signal to indicate a valid bus cycle. When valid,
RWT = 0. The Address, Data, and the BIU signals are
effective when this signal is 0.
Shows the status between the CPU and BIU (Bus Interface
Unit).
Shows the op-code size in the read data.
Shows the code size except op-code.
