J-Mem displays memory contents of ARM systems and allows modifications of RAM and SFRs (Special Function Registers) while the target is running. This makes it possible to look into the memory of an ARM chip at run-time; RAM can be modified and SFRs can be written. The type of access for both read and write access can be selected to be 8/16/32 bits. This is an efficient means for modifying SFRs, in particular because it writes the SFR only after the complete value has been entered.
