Explanation of each area

1 ) [Trace]

Sets up the trace mode of task analyzer.


Selection of trace mode	Select trace mode of Realtime OS Task Analyzer
	Default	Not tracing
	How to change	Select from the drop-down list.
	Restriction	Not tracing	Can not use Realtime OS Task Analyzer.
		Taking in trace chart by hardware trace mode	The trace information is collected in the trace memory which emulator or simulator has.
		Taking in trace chart by software trace mode	The trace information is collected in the trace buffer secured on the user memory area. To use this mode, implementation of user-own coding module and setup of the system configuration file are required.
		Taking in longstatistics by software trace mode	The trace information is collected in the RI78V4's variable secured on the user memory area. To use this mode, the trace buffer is allocated in ".kernel_data_trace_n" section.
Operation after used up the buffers	Select the operation after user up the trace buffer. This item is displayed only when "Taking in trace chart by software trace mode" is selected.
	Default	Continue to exection while the buffers overwriting.
	How to change	Select from the drop-down list.
	Restriction	Continue to exection while the buffers overwriting	It is overwritten sequentially from old information.
		Stop the trace taking in	The RI78V4 stops tracing.
Buffer size	Specify the size of the trace buffer (in bytes). Please refer to "15.4 Trace Buffer Size (Taking in Trace Chart by Software Trace Mode)" for the estimate of the size of the trace buffer. This item is displayed only when "Taking in trace chart by software trace mode" is selected.
	Default	0x100
	How to change	Directly enter to the text box. Only a hexadecimal number can be entered.
	Restriction	0xa0xfffe
