S5U1C33001H
TECHNICAL INFORMATION
Flash Programmer Function
The flash programmer function allows writing data such as programs, which have been downloaded into the
S5U1C33001H's internal flash memory, to the target system's flash memory directly from the S5U1C33001H.
The flash programmer function is enabled by setting DIP switches 1 and 7 on the S5U1C33001H. The function is disabled
in the default setting.
Setting the DIP switch:
Refer to the "DIP Switches" section.
Download procedure and commands used:
Refer to the "Flash Writer Commands" section in the "S5U1C33001C Manual (C Compiler Package for S1C33 Family)".
Procedure for converting files to be written to the target system flash memory into Motorola S3 files:
Refer to the "Creating ROM Data" section in the "S5U1C33001C Manual (C Compiler Package for S1C33 Family)". See
also the above manual for details on creating program files for writing to flash memory on the target system.
• Downloading to the target system flash memory
(1) Turn the S5U1C33001H on.
(2) Turn the target system on.
(3) Invoke the debugger (gdb.exe) and download the write data file to the
S5U1C33001H.
(4) When the download has completed, turn off the S5U1C33001H and target system,
and set the S5U1C33001H DIP switches to "flash programmer enabled (erase and
write mode)".
(5) Turn on the S5U1C33001H and target system, and set the RESET/WRITE switch
to the ON position.
(6) The ERASE LED lights and the target system flash memory is erased. The BUSY
LED lights during the erase operation.
(7) The WRITE LED lights and data are written to the target system flash memory. If
the data being written is a small program, this operation will complete instantly.
The BUSY LED also lights during the write operation.
(8) The OK LED lights when the operation has completed normally.
(9) If another target system is to be programmed, the S5U1C33001H's power must be
turned off before programming that target system.
• Verifying the data downloaded to the target system
(1) Perform steps (1) to (8) in the download procedure shown above to write data.
This operation is not necessary when verifying data immediately after the down-
load has completed.
(2) When the download has completed, turn off the S5U1C33001H and target system,
and set the S5U1C33001H DIP switches to "flash programmer enabled (verify
mode)".
(3) Turn on the S5U1C33001H and target system, and set the RESET/WRITE switch
to the ON position.
This starts verification of the downloaded data. The BUSY LED lights during the
verify operation.
(4) The OK LED lights when the written data matches.
If the written data does not match, the ERROR LED lights.
