Address Breaks
6.7.1
Features
With this LSI, 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.
