CHAPTER 16: DEBUGGER
Trace function in ICD mode

(1) Trace memory and trace information
(2) Trace mode and trace condition
1. All trace mode
The S5U1C33000H contains a trace memory that has the capacity to store information for 131072 cycles.
The S5U1C33000H stores the information of instruction execution cycles in the trace memory using the
debugging signals output from the S1C33 chip and other methods.
The following lists the trace information that is taken into the trace memory in every cycle. This list is
corresponded to display in the [Trace] window.
Cycle:
Address:
Code:
Unassemble: Disassembled content of the instruction code
Clk:
Method:
File:
Line:
SourceCode: Source code
Two trace modes are available, depending on the trace range.
In this mode, trace is initiated by a start of program execution. It continues until a break occurs when "with
overwriting" is selected as the trace condition. If the trace memory becomes full, the oldest data will be
overwritten with the new trace data. If the trace condition is set to "without overwriting", trace is terminated
when the trace memory is full.
Trace cycle (decimal)
The last information taken into the trace memory becomes 000000.
CPU-instruction-execution address (hexadecimal)
Instruction code executed by the CPU (hexadecimal)
Number of clocks used for executing the instruction
By default, the cumulative clock count from start of tracing is displayed. It can be changed so
that the number of clocks for each executed instruction is displayed.
Trace analytical method (to get the executed PC address)
Source file name (which includes the executed instruction)
Source line number
SPC:
TRG: Analyzed with the trigger address
DPC:
RET:
MAP: Analyzed with the map information
RTI:
---:
Analyzed with the start PC address
Analyzed with the DPCO signal
Analyzed with the call/ret statement
Analyzed with the reti statement
Cannot be analyzed
