4.1.1 Target Interface Connector

The 4-pin target interface connector (black) on the S5U1C17001H is used to input/output the debug signals from/
to the S1C processor on the target system. Use the target interface cable attached to the S5U1C17001H to connect
between this connector and the target system. This connection is always required to perform debugging. The pin
assignment of the 4-pin connector (black) on the S5U1C17001H is shown in the table below. For the debug pin
numbers on the S1C processor, refer to the technical manual of each model.

Figure 4.1.1.1 Connecting the Target System

Notes: • Set the interface level (3.3 V/1.8 V/target input) using the DIP switches SW4 and SW5, and

select the CPU Core using the SW1 according to the target system before connecting the tar­get system.

• The signals connected to the S5U1C17001H are very high-speed signals, so the connector

on the target system must be mounted within 5 cm from the S1C processor. If there is more
distance between the connector and the S1C processor, the S5U1C17001H may not work
properly.

• When wiring the S1C processor to the target connector for connecting the S5U1C17001H, in-

sert a 33 W resistor in series between the S1C processor DSIO pin and the connector. This re­sistor must be placed as close to the S1C processor as possible. Although the system can op­erate without this 33 W resistor, we recommend inserting this resistor to prevent malfunctions.
The other pins are connected directly. A low-level input to the DSIO pin issues a forced break
to set the S1C processor into debug mode. Although this signal is pulled up through about 100
kW internally, when not debugging, we recommend either removing the 33 W resistor to reduce
noise and other problems or pulling this line up to the VDD level (the core voltage).

• Be sure to use the supplied 4-pin cable for connecting the target system to the S5U1C17001H.

Using another cable may cause a malfunction. If another cable must be necessarily used, do
not extend the target interface cable and connect the cable directly to the S5U1C17001H so
that the distance to the S1C processor on the target system will be shortest.

• The 4-pin connector does not have a projection for preventing reverse insertion. Check the

cable color (blue) of pin 1 to be sure the insertion of connector is proper when connecting it to
the target system.

4.1.2 Flash Programming Power Supply Connector

The 4-pin Flash programming power supply connector (white) is used to output a reset signal and a Flash pro­gramming voltage to the target system, and to input the target interface voltage. These signals are not necessary
for debugging. Connect between this connector and the target system using the Flash programming power sup­ply cable attached to the S5U1C17001H as necessary. The pin assignment of the 4-pin connector (white) on the
S5U1C17001H is shown in the table below.

Target voltage input (TARGET VCC IN)

In addition to 3.3 V and 1.8 V, the S5U1C17001H is capable of interfacing with the target system using the

voltage (1.0 to 5.0 V) input from the target system. To use this function, set SW4 to ON and input the target
voltage to the TARGET VCC IN pin.

Flash programming voltage output (FLASH VCC OUT)

Depending on the Flash memory module built into the S1C processor on the target system, its programming

voltage (7 V) can be supplied from the S5U1C17001H. The maximum current that can be supplied is 200 mA.

To use this output, set SW8 to ON and connect between the FLASH VCC OUT pin and the power supply pin

on the target system. When SW8 is set to ON, the FLASH VCC OUT pin always outputs a 7-V voltage regard­less of whether the RESET/START switch is pressed or not.

Note: Refer to the technical manual of each model as to whether the target S1C processor is operable

with this voltage or not. Do not use this voltage unless there is a description about the usage in
the technical manual, as the S1C processor may be destroyed due to overvoltage.

(ICD MINI VER. 1.0)

6 Flash Programmer Mode

Flash programmer mode is an S5U1C17001H operating mode for using it as a standalone Flash programmer. The
following explains the settings for activating the Flash programmer mode and operations.

6.1 Preparation for Flash Programming

The Flash programming feature allows programming the target system’s Flash memory with data such as a pro­gram, which has been downloaded into the S5U1C17001H’s internal Flash memory.
First download the data to program the target system’s Flash memory into the S5U1C17001H by the procedure de­scribed below.

(1) Convert the file for programming the Flash memory into a Motorola S3 file.
Use “objcopy.exe” included in the S1C17 Family C Compiler Package for file conversion.
Example: 1. Convert “sample.elf” into a Motorola S3 file.
>objcopy -O srec -R .gbss --srec-forceS3 sample.elf sample.sa

2. Fill the unused addresses in “sample.sa” and generate “sample.saf.”
(when the start address and block size to be filled are 0x8000 and 0x1000, respectively)
>moto2ff 0x8000 1000 sample.sa

(2) Start up the S5U1C17001H in ICD mode (see Section 5.2).

(3) Start up the debugger.

1. Launch GDB.
>gdb

2. Connect the target.
(gdb) target icd usb

(4) If the S5U1C17001H contains an unnecessary program/data used previously, clear it using the c17 fwe com-

mand.

(5) Download a Flash erase/program routine into the S5U1C17001H using the c17 fwlp command.
Example: Load the data erase/write program file “writer.sa.”
(when the erase routine start address is 0x4c and the write routine start address is 0x80)
(gdb) c17 fwlp writer.sa 0x4c 0x80

(6) Download the data for programming the target system’s Flash memory into the S5U1C17001H using the c17

fwld (or c17 fwdc) command. At the same time, specify the range of the Flash memory to be erased.

Example: Erase all sectors and load “sample.saf” to the Flash.
(when the Flash start address is 0x8000)
(gdb) c17 fwld sample.saf 0 0 0x8000

(7) Quit the debugger.

For details of the debugger (gdb.exe) and “objcopy.exe,” refer to the “S5U1C17001C Manual (C Compiler Package

8 PRECAUTIONS

S5U1C17001H USER MANUAL

EPSON

19

(ICD MINI VER. 1.0)

8 Precautions

8.1 Restrictions on Debugging

The debugging using the S5U1C17001H is subject to the restrictions specified below.

Operation of the internal peripheral circuits

The peripheral circuits of the target S1C processor 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. For details
on single-step execution, refer to the “Debugger” section in the “S5U1C17001C Manual (C Compiler Package
for S1C17 Family)”.

Interrupts when the target program is not running

If an interrupt request to the S1C Core is generated by the target system when the target program is not running,

interrupt processing is paused. The interrupt that has been paused is serviced immediately before the target
program is executed or immediately after one instruction is executed after the debugger (gdb.exe) on the host
computer has directed that the target program be executed.

Interrupts when the target program is executed in a single step

If an interrupt request to the S1C Core is generated by the target system during single-step execution of the

target program, including functions and subroutines (STEP), the interrupt request is paused. During single-step
execution of the target program, not including functions and subroutines (NEXT), an interrupt request received
within a function or subroutine is serviced without being paused and an interrupt received in other parts of the
program is paused as with the STEP command. The interrupt that has been paused is serviced immediately be­fore the target program is executed or immediately after one instruction is executed after the debugger (gdb.exe)
on the host computer has directed that the target program be executed. For details on single-step execution (STEP
and NEXT), refer to the “Debugger” section in the “S5U1C17001C Manual (C Compiler Package for S1C17
Family)”.

Execution counter

The execution counter is capable of measuring execution times up to 6515 hours with a ±1 µs of measurement

error. A 3 µs or less of program execution time cannot be measured correctly.

The counter is also used for clocking of the lapse of time break function, therefore, execution times cannot be

measured when the lapse of time break function is used.

Reset sequence

The sequence from when the S5U1C17001H is powered on until the target program is executed is entirely dif-

ferent from that of the actual S1C processor.

However, a sequence for the reset request input from the target system while the target program is being ex-

ecuted is the same as that for the actual S1C processor.

Regarding the reset sequence in the actual S1C processor, refer to the technical manual of each model.

Break functions when a reset request is accepted

If a reset request (reset input or reset interrupt from the watchdog timer) is accepted while the S1C processor

on the target system is executing the target program in normal mode, the hardware PC break and software PC
break functions are disabled. It will be enabled again when the S1C processor enters debug mode.

I/O memory dump by the S5U1C17001H

Note that some S1C peripheral circuits may change the control register status due to their specifications when

the I/O memory is read using the memory dump function of the S5U1C17001H or when the target program ex­ecution is suspended.

For details on the memory dump function, refer to the “Debugger” section in the “S5U1C17001C Manual (C

Compiler Package for S1C17 Family)”.

20

EPSON

S5U1C17001H USER MANUAL

(ICD MINI VER. 1.0)

8.2 Differences from the Actual IC

The S5U1C17001H 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.

Register initialization

The initial CPU register values may be different from those of the actual IC. Therefore, be sure not to create a

program that depends on the initialized value.

The initial values when the S5U1C17001H is connected are as follows:
r0–r7: 0x000000
pc: 0x008000

(Note)

sp: 0xfffffc
psr: 0x00 (IL = 000, IE = 0, CVZN = 0000)

Note: The PC initial value is decided according to the TTBR register setting value (boot address). Refer

to the technical manual of each model for the TTBR value.

8.3 Notes on Use of S5U1C17001H

Powering on/off

After turning off the power to the S5U1C17001H by disconnecting the USB cable, wait at least 10 seconds

before turning the power on (connecting the USB cable) again. If the power is turned on immediately after it is
turned off, the S5U1C17001H may not be initialized correctly in a power-on reset, and may cause a malfunc­tion.

Connecting the target system

The signals connected to the S5U1C17001H are very high-speed signals, so the connector on the target system

must be mounted within 5 cm from the target S1C processor. If there is more distance between the connector
and the S1C processor, the S5U1C17001H may not work properly. Furthermore, be sure to use the supplied
4-pin cable for connecting the target system to the S5U1C17001H. Using another cable may cause a malfunc­tion. If another cable must be necessarily used, do not extend the target interface cable and connect the cable
directly to the S5U1C17001H so that the distance to the S1C processor on the target system will be shortest.

Operation of the S5U1C17001H system

The S5U1C17001H can work by connecting a target system in which the actual S1C processor is mounted.

Since the S5U1C17001H package does not include any board equivalent to a target system, please prepare
separately.

Wiring between the S1C processor and target connector

When wiring the S1C processor to the target connector for connecting the S5U1C17001H, insert a 33 W resis-

tor in series between the S1C processor DSIO pin and the connector. This resistor must be placed as close to the
S1C processor as possible. If the reset line is not connected, the system can be operated without this 33 W resis­tor. However, we recommend inserting this resistor to prevent malfunctions. The other pins are connected di­rectly. The total length of the line must be under 5 cm. A low-level input to the DSIO pin issues a forced break
to set the S1C processor into debug mode. Although this signal is pulled up through about 100 kW internally,
when not debugging, we recommend either removing the 33 W resistor to reduce noise and other problems or
pulling this line up to the VDD level (the core voltage).

(ICD MINI VER. 1.0)

Reset request

Do not reset the target system while the target program execution is suspended as the S5U1C17001H will be

unable to operate normally.

Notes on target system power supply

The allowable voltage range for the signals input from the target system is 0 to 5.5 V. The S5U1C17001H may

fail if voltages that exceed this range are input. Therefore, target systems to be connected to the S5U1C17001H
must be designed so that voltages outside this range are not applied. Take special care in designing the target
system power supply, and design the target system so that overvoltages are not applied to the S5U1C17001H
when the target system power supply is turned on or off.
