Section 5 Interrupt Controller
5.4
5.4.1
With the H8S/2138 Group and H8S/2134 Group, it is possible to identify the prefetch of a specific
address by the CPU and generate an address break interrupt, using the ABRKCR and BAR
registers. When an address break interrupt is generated, address break interrupt exception handling
is executed.
This function can be used to detect the beginning of execution of a bug location in the program,
and branch to a correction routine.
5.4.2
A block diagram of the address break function is shown in figure 5.5.
