Section 3. Emulation Functions
3.1 Overview
3.1.1 Emulation
The CE2000-H8S/2238 emulator operates in two modes: Break and User modes.
To execute the user program, user can either
Single - Step , Run at current program counter or Reset Go . This
will cause it to operate in the User mode . To terminate the User Run state, a break condition has to be
asserted to bring the emulator to the Break mode . This can either be a preset condition(eg. PC Break,
Event Break) or a force break condition (Hit ESC key).
During Break mode, user can manipulate their target system & memory by accessing the I/O, Memory
… windows.
During Run mode, information such as accessed address, CPU states (e.g. instruction fetch cycle, sleep
mode…) and run time can be observed. User can also view and edit the memory contents in the internal
ROM/RAM or optional SODIMM area. This process is named as Parallel On the Fly (POTF).
