3.5 J-Mem Memory Viewer
J-Mem displays memory contents of target systems and allows modifications of RAM
and SFRs (Special Function Registers) while the target is running. This makes it pos-
sible to look into the memory of a target system at run-time; RAM can be modified
and SFRs can be written. You can choose between 8/16/32-bit size for read and write
accesses. J-Mem works nicely when modifying SFRs, especially because it writes the
SFR only after the complete value has been entered.
