5. CONNECTION 5.3 Connector for flash programmer power supply This connector is used to output reset signals to the target system, to output voltage for flash programming, and to input target interface voltage. Debugging is possible without connecting these signals. If necessary, use the cable for flash programmer power supply provided with the S5U1C33001H to connect the target system. The pin assignment of the 4-pin connector (white) of the S5U1C33001H is shown in the table below.
5. CONNECTION 5.3.3 Flash programming voltage output (FLASH VCC OUT) Some target S1C processors have internal flash memory that can supply the voltage (7 V) necessary for flash programming from the S5U1C33001H. The maximum current that can be provided in this way is 200 mA. To use this output, set the DIP SW8 to ON and connect the power supply from the target system to the FLASH VCC OUT pin.
6. START-UP METHOD (POWER-ON SEQUENCE) 6. START-UP METHOD (POWER-ON SEQUENCE) To start up the S5U1C33001H system, follow the sequence described below: (1) Connect the S5U1C33001H to the host computer using the USB cable. The LED1, LED2, and LED3 operate as follows: LED1 (Green, ON) * In the case of C33 LED2 (Red, ON) LED3 (OFF) (2) Turn the target system on.
6. START-UP METHOD (POWER-ON SEQUENCE) communication between the S5U1C33001H and the target system may be disconnected after the second reset. Design the target system so that switch bounce does not occur and the system starts up only once. Furthermore, if the reset is applied with either the power or the oscillator in an unstable state (for example, if the reset is applied within the first few ms after the power is turned on), the S1C33xxx chip operation will also be unstable.
7. ICD MODE 7. ICD MODE ICD mode is used to debug the target system by connecting the debugger (dbg.exe) on the PC to the target system. Described below are the settings for launching the S5U1C33001H in ICD mode and corresponding procedures. 7.1 ICD mode setting To launch the S5U1C33001H in ICD mode, set the DIP switches as follows: SW2 = OPEN SW3 = OPEN 7.2 Invoking ICD mode After Connecting the target system to the host computer, start the S5U1C33001H as described below.
7. ICD MODE < When TARGET RST_OUT signal is connected > If the TARGET RST OUT signal is connected to reset the target system, the S5U1C33001H automatically generates signals according to the connection procedure. You need only to press the S5U1C33001H RESET/START switch to start the S5U1C33001H. (1) Press the S5U1C33001H RESET/START switch.
8. FLASH PROGRAMMER MODE 8. FLASH PROGRAMMER MODE Flash programmer mode lets the S5U1C33001H function as a flash programmer. Described below are preparations for starting up the S5U1C33001H in flash programmer mode and associated procedures. 8.1 Preparing for flash programming The S5U1C33001H can write data, such as a program downloaded to internal flash memory, directly to the flash memory of the target system.
8. FLASH PROGRAMMER MODE (6) Use the c33 fwld (or c33 fwdc) command to download the data to be written to the target system flash memory to the S5U1C33001H. At the same time, set the erase area in flash memory. Example: Erasing all sectors and downloading sample.saf to flash memory (when flash start address is 0x600000) (gdb) c33 fwld sample.saf 0 0 0x600000 (7) End the debugger. For an in depth discussion of the debugger (dbg.exe) and objcopy.

9. FIRMWARE UPDATE PROCEDURE 9. FIRMWARE UPDATE PROCEDURE The S5U1C33001H has a firmware update function using the debugger (gdb.exe). The following show the procedure to update the S5U1C33001H firmware. Note: Before the firmware can be updated, the USB driver must be installed. (1) Connect the S5U1C33001H with the host computer using the USB cable. (2) Set the S5U1C33001H DIP switches as shown below and press the RESET/START switch. SW2 = OPEN SW3 = OPEN SW7 = ON (3) Invoke the debugger (gdb.
10. PRECAUTIONS 10. PRECAUTIONS 10.1 Restrictions on debugging The debugging using the S5U1C33001H is subject to the restrictions specified below. 10.1.1 Operation of the internal peripheral circuits The peripheral circuits of the S1C33xxx stop operating when the debugger (gdb.exe) on the host computer is ready to accept commands, that is, unless the target program is running. For this reason, the peripheral circuits do not operate in real time when the target program is executed in the single-step mode.
10. PRECAUTIONS (2) Break functions that suspend the target program after several instructions are executed from the instruction in which the cause of the break occurred Data break, area break, bus break For details on break functions, refer to the “Debugger” section in the “S5U1C33001C Manual (C Compiler Package for S1C33 Family)”. 10.1.5 Trace function Note that the trace function in the S5U1C33001H has the following restrictions.
10. PRECAUTIONS 10.1.7 Reserved areas in the internal peripheral circuits (C33 STD/Mini core) When reserved areas in the internal peripheral circuits are displayed using the S5U1C33001H’s data display function, note that, depending on the type of microcomputer, the last value read by the C33 core that is held in the bus latch circuit inside the chip may be displayed. 10.1.
10. PRECAUTIONS 10.1.11 Reset sequence The sequence from when the S5U1C33001H is powered on until the execution of the target program is executed is entirely different from that of the actual S1C33xxx chip. However, a sequence for the reset requests input from the target system while the target program is being executed is the same as that for the actual S1C33xxx chip. Regarding the reset sequence in the actual S1C33xxx chip, refer to the “S1C33xxx Technical Manual”. 10.1.
10. PRECAUTIONS 10.1.15 Models with cache memory embedded The debugging operations performed while program execution is suspended rewrite the contents of the cache memory. Furthermore, the software PC break function cannot be used when the cache is used under conditions other than that listed in the table below. Use the hardware break function in such cases.
10. PRECAUTIONS 10.2 Differences from the actual IC The S5U1C33001H is different from the actual IC in the way specified below. If this difference is not taken into consideration in an application, the program may not operate normally in the actual IC. 10.2.
10. PRECAUTIONS 10.3 Usage precautions 10.3.1 Connecting and disconnecting equipment Before attaching or removing the target system and cables, and setting the DIP switch and jumper, be sure to turn off the power to the host computer, S5U1C33001H, and target system. Failure to take this precaution may result in equipment malfunction. 10.3.2 Powering on/off After turning off the power to the S5U1C33001H, wait at least 10 seconds before turning the power on again.
10. PRECAUTIONS 10.3.5 Wiring between the S1C33xxx chip and target connector When wiring the S1C33xxx chip to the target connector for connecting the S5U1C33001H, insert a 33 Ω resistor in series between the S1C33xxx chip DSIO pin and the connector. This resistor must be placed as close to the S1C33xxx chip as possible. If the reset line is not connected, the system can be operated without this 33 Ω resistor. However, we recommend inserting this resistor to prevent malfunctions.
10. PRECAUTIONS 10.3.8 Notes on S5U1C33001H power supply When using the S5U1C33001H, install circuit breakers that automatically disconnect both conductors in the local power mains, and connect the S5U1C33001H power supply line to a power line protected in that manner. 10.3.9 Core Sync Simple Logic Analyzer Function This function allows tracing of up to 14 arbitrary signals in the same cycles as the core clock. The traced information can be displayed with the core status.
10. PRECAUTIONS 10.4 Implementation of the PC trace function The PC trace function is implemented by a method that allows the debugger (gdb.exe) to analyze the target program flow using the information delivered on the DST0, DST1, DST2 and DPCO signals output from the S1C33xxx chip, and the target program information loaded into the debugger. The debugger obtains the absolute addresses information required for analyzing the target program flow from the following status.
11. TROUBLESHOOTING 11. TROUBLESHOOTING The following shows the problems attributable to the hardware: Table 9 Troubleshooting Symptom Cause/remedy After power is supplied to the S5U1C33001H via USB, the LED2 (EMU) does not change to ICD mode (blue).
