Section 2 Software Specifications when Using the SH72546RFCC, SH72544R, SH72543R, SH72531FCC,
and SH72531
• Halting a trace
Do not set the trace end condition for the sleep instruction and the branch instruction that the
delay slot becomes the sleep instruction.
• Trace acquisition condition
Do not set the trace end condition for the sleep instruction and the branch instruction according
to which the delay slot becomes the sleep instruction.
When [F-Bus], [F-Bus, M-Bus & Branch], or [I-Bus, F-Bus] is selected, do not set the trace
acquisition condition for [Event Condition 1] and [Event Condition 2]. If a trace acquisition
condition is set, no trace will be acquired.
When [I-Bus, M-Bus & Branch] is selected and the trace acquisition condition is set for the M-
bus and I-bus with Event Condition, set the M-bus condition and the I-bus condition for [Event
Condition 1] and [Event Condition 2], respectively.
When matching of the program counter value is a condition of Event Condition for internal
trace acquisition (i.e. [Only program fetched address] or [Only program fetched address after]
is selected), do not specify addresses in the on-chip ROM or on-chip RAM as the address
condition.
If you specify a break (by selecting the [Acquire Break] checkbox) and trace acquisition (by
selecting [Condition] from the [Acquire Trace] list box) on the [Action] page as the action to
take when a condition of Event Condition is satisfied, setting of the trace acquisition will be
ignored.
If the settings of [I-Trace mode] are changed during execution of the program, execution will
be suspended. (The number of clocks to be suspended during execution of the program is a
maximum of about 24 peripheral clocks (Pφ). If the peripheral clock (Pφ) is 66.6 MHz, the
program will be suspended for 0.36 μs.)
• Displaying a trace
If a trace is displayed during execution of the program, execution will be suspended to acquire
the trace information. (The number of clocks to be suspended during execution of the program
is a maximum of about 5120 peripheral clocks (Pφ). If the peripheral clock (Pφ) is 66.6 MHz,
the program will be suspended for 76.87 μs.)
• Branch trace
If breaks occur immediately after executing non-delayed branch and TRAPA instructions and
generating a branch due to exception or interrupt, a trace for one branch will not be acquired
immediately before such breaks.
However, this does not affect on generation of breaks caused by a BREAKPOINT and a break
before executing instructions of Event Condition.
