In this example, after setting in reset mode, the execution counter is reset by the reset command, thereby

starting the program. In reset mode, the execution counter is reset when program execution resumes after a

break. Therefore, counts in this mode differ from those in cumulating mode.

• In ICD Mini mode, the continue/until command must be executed before this command becomes

In simulator mode, this command is always effective.

• The c17 clock command cannot display execution times while the lapse of time break (c17 timebrk)

is enabled. Disable the lapse of time break (c17 timebrk 0) to measure execution times.

• The execution counter is reset in the following cases:

1. When the c17 clockmd command changes execution counter mode (from cumulating mode to reset

mode or vice versa)

2. When the program is started with the counter set to reset mode

3. When the CPU is reset

4. When the c17 timebrk, step, stepi, next, nexti or finish command is executed in ICD

• Deviations of about 30 to 40 cycles will occur in ICDmini mode because it includes debugging mode

entering and exiting processes.
