6.3.5 Setting a Breakpoint

(1) Scroll the source code display to show line 47 by using the scroll bar.

Double-click line 47

Figure 6.24 Setting a Hardware Break

Here, double-click the [Event] column on line 47 to set a break condition.

A blue dot indicates that a break condition has been set.

To clear a break condition previously set, double-click the blue dot.

During debugging of the H8/3664F program through the E8 emulator, only one breakpoint can be set as an [Event]-

type break. This type of break is advantageous because it does not require write access to the on-chip flash memory

of the H8/3664F to set or clear a break condition, since it is implemented by hardware (a hardware break), and thus

does not degrade flash memory endurance.

In contrast, software break conditions can be set for up to 255 points, but the flash memory is written to every time

a condition is set or cleared.
