Section 2 Software Specifications when Using the SH72546RFCC, SH72544R, SH72543R, SH72531FCC,
and SH72531
Set the condition to be acquired on [I-Trace mode].
Set the address condition as H’1000 in the [Event Condition 5] dialog box.
Set the address condition as H’2000 in the [Event Condition 4] dialog box.
Set [I-Trace] as [Ch5 to Ch4 PtoP] in the [Combination action (Sequential or PtoP)] dialog
box.
When point-to-point and trace acquisition condition are set simultaneously, they are ANDed.
(2) Notes on Internal Trace
• Timestamp
The timestamp is the clock counts of Pφ (48-bit counter). Table 2.13 shows the timing for
acquiring the timestamp.

• Point-to-point
The trace-start condition is satisfied when the specified instruction has been fetched.
Accordingly, if the trace-start condition has been set for the overrun-fetched instruction (an
instruction that is not executed although it has been fetched at a branch or transition to an
interrupt), tracing is started during overrun-fetching of the instruction. However, when
overrun-fetching is achieved (a branch is completed), tracing is automatically suspended.
If the start and end conditions are satisfied closely, trace information will not be acquired
correctly.
The execution cycle of the instruction fetched before the start condition is satisfied may be
traced.
When the I-bus is acquired, do not specify point-to-point.
Memory access may not be acquired by the internal trace if it occurs at several instructions
immediately before satisfaction of the point-to-point end condition.
