26.2 Reserved Area Used by QB-MINI2
QB-MINI2 uses the reserved areas shown in Figure 26-4 below to implement communication with the 78K0/Kx2-A
microcontrollers, or each debug function. The shaded reserved areas are used for the respective debug functions to
be used, and the other areas are always used for debugging. These reserved areas can be secured by using user
programs and compiler options.
When using a boot swap operation during self programming, set the same value to boot cluster 1 beforehand.
