When the td command is input without <num>, the debugger displays 11 lines of the latest trace data
in the [Command] window. When the td command is input with <num>, the debugger displays 11
lines of the trace data from <num> in the [Command] window.

  • Trace memory has a capacity of 8,192 cycles. On the other hand, the S1C6200 has 5, 7 and 12 clock

instructions. The 5 clock instructions require 3 bus cycles, 7 clock instructions require 4 bus cycles, and
12 clock instructions require 6 bus cycles. Thus, the final value of the trace pointer is changed accord-
ing to the executed instruction. The maximum final value when only 5 clock instructions are executed
is about 2,730, while the execution for only 12 clock instructions is about 1,300. So the maximum
possible value of trace pointer is 2,730.
An error results if the <num> you specified exceeds the maximum possible value (2,730).

  • The trace memory receives new data until a break occurs. When the trace memory is filled, old data is

overwritten by new data.

  • If there is no trace information can be read out, the warning message will be displayed.

No trace data.

  • An error results if the <num> value you input is bigger than the last location in the trace memory.

Error : Data address out of range.

When this menu item is selected, the [Trace] window opens and displays the latest trace data.
