All RH850 devices support memory access during runtime using the command SYStem.MemAccess CPU.

So It is possible to read from memory, to write to memory and to set software breakpoints while the CPU is executing the program.

During "running" mode:
- Software breakpoints can be set/modified.
- Onchip breakpoints cannot be set/changed. This is RH850 chip restriction.
With the command SYStem.CpuBreak Enable, TRACE32 will do a quick STOP→ Set/Clear Breakpoints → GO when breakpoints are set/changed.
- Global variables can be viewed and modified.
