Free-run of S5U1C33104H
The S5U1C33104H in-circuit emulator contains flash memory. This memory is designed to allow data to be
transferred to and from the S5U1C33104H internal ROM emulation memory by a command.
The flash memory retains data even when the S5U1C33104H is turned off. By writing the program, data,
option data and map information under debug into the flash memory before turning off the power, you can
call it up and continue debugging next time. Also, even when operating the S5U1C33104H in free-run mode
(in which a program is executed using only the S5U1C33104H), you may need to write the program into the
flash memory.
The following operations can be performed on the flash memory:
Data is loaded from the flash memory into the internal ROM emulation memory.
Data in the internal ROM emulation memory is saved to the flash memory. Also, the contents of the
parameter file can be written to the flash memory as necessary. After writing to the flash memory in this
way, you can protect it against read and write.
All contents of the flash memory are erased.
The flash memory map, chip name, version of the parameter file used and other information are displayed.
The flash memory can only be altered in ICE mode.
When operating the S5U1C33104H in free-run mode (with the program executed using only the
S5U1C33104H), the S5U1C33104H uses the data written in the flash memory. Therefore, before the
S5U1C33104H can be used in free-run mode, the entire program, data, and option data must be written into
the flash memory. However, data not in the internal ROM cannot be saved.
To operate the S5U1C33104H in free-run mode, set the ICE/RUN switch to the RUN position and turn on
the power. During free-run, map breaks caused by operation in the program and data areas set by a
parameter file are effective. When a map break occurs, the PC LED on the S5U1C33104H stops and the
EMU LED turns off. All other break settings are invalid because they cannot be written into the flash
memory.
