• 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 [I-BUS, M-Bus & Branch] is selected and the trace acquisition condition is set for the

M-bus and I-bus with the Event Condition, set the M-bus condition and the I-bus condition for

[Event Condition 1] and [Event Condition 2], respectively.

If the settings of [I-Trace mode] are changed during execution of the program, execution will

be suspended. (The number of clock cycles to be suspended during execution of the program is

a maximum of about 51 peripheral clock cycles (Pφ) + 15 bus clock cycles (Bφ). If the

peripheral clock (Pφ) is 33.3 MHz and the bus clock (Bφ) is 66.6 MHz, the program will be

suspended for 1.757 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 clock cycles to be suspended during execution of the

program is a maximum of about 20480 peripheral clock cycles (Pφ) + 4096 bus clock cycles

(Bφ). If the peripheral clock (Pφ) is 33.3 MHz and the bus clock (Bφ) is 66.6 MHz, the

program will be suspended for 676.52 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.
