Figure 6.24 Setting an Event Break

Here, double-click the [Event] column on line 41 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 R8C/1B program through the E8 emulator, up to four breakpoints 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 R8C/1B to set or clear a break condition, since it is implemented by the debug circuit of the R8C/1B,

and thus does not lower the write-access speed of the flash memory.

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.
