2. Outline of the Sample Projects
The Smart Configurator for RH850/F1KM devices outputs a main function and source files that initialize peripheral
modules that were set by components of the Smart Configurator. After the microcontroller has been reset, the
initialization processing that is to be performed before execution of the main function and the startup routine that starts
the main function and handles other processing are not output.
Therefore, we have prepared sample projects that include startup of the sample projects so that code for peripheral
modules according to the settings in the Smart Configurator and user applications employing this code can be built
immediately.
2.1 List of Sample Projects
The Smart Configurator for RH850/F1KM devices provides the following sample projects.
For details on the sample projects, see the descriptions in the relevant sections.

2.2 Notes on the Sample Projects
1. The Smart Configurator outputs the reg ister descriptors according to iodefine.h for the Renesas CCRH compiler.
Though header files of register definitions are also prepared in the GHS CCRH850 and IAR ICC compilers, include
iodefine.h for the Renesas CCRH compiler when building files generated by the Smart Configurator.
2. The Smart Configurator uses interrupts with the table lookup method as the method for selecting the interrupt
handler addresses. The address where the table starts is set as 0x00000200 in the sample projects.
3. The definition of the interrupt vector table of peripheral modules that was set in the Smart Configurator is reflected
in smc/general/r_cg_intvector.c, which is output by the Smart Configurator. The file sc_intprg-S1.c or sc_intprgS4.c in the intprg folder defines the vector table of EI maskable interrupt sources, which is not set by the Smart
Configurator.
4. Settings of files and sections provided with the sample projects are examples. They should be changed or created
newly by yourself to match the specifications of the microcontroller in use and the customer's system.

Revision History
General Precautions in the Handling of Microprocessing Unit and Microcontroller
Unit Products
The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from Renesas. For detailed usage notes on the
products covered by this document, refer to the relevant sections of the document as well as any technical updates that have been issued for the products.
1. Precaution against Electrostatic Discharge (ESD)
A strong electrical field, when exposed to a CMOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps
must be taken to stop the generation of static electricity as much as possible, and quickly dissipate it when it occurs. Environmental control must be
adequate. When it is dry, a humidifier should be used. This is recommended to avoid using insulators that can easily build up static electricity.
Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and
measurement tools including work benches and floors must be grounded. The operator must also be grounded using a wrist strap. Semiconductor
devices must not be touched with bare hands. Similar precautions must be taken for printed circuit boards with mounted semiconductor devices.
2. Processing at power-on
The state of the product is undefined at the time when power is supplied. The states of internal circuits in the LSI are indeterminate and the states of
register settings and pins are undefined at the time when power is supplied. In a finished product where the reset signal is applied to the external reset
pin, the states of pins are not guaranteed from the time when power is supplied until the reset process is completed. In a similar way, the states of pins
in a product that is reset by an on-chip power-on reset function are not guaranteed from the time when power is supplied until the power reaches the
level at which resetting is specified.
3. Input of signal during power-off state
Do not input signals or an I/O pull-up power supply while the device is powered off. The current injection that results from input of such a signal or I/O
pull-up power supply may cause malfunction and the abnormal current that passes in the device at this time may cause degradation of internal
elements. Follow the guideline for input signal during power-off state as described in your product documentation.
4. Handling of unused pins
Handle unused pins in accordance with the directions given under handling of unused pins in the manual. The input pins of CMOS products are
generally in the high-impedance state. In operation with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of
the LSI, an associated shoot-through current flows internally, and malfunctions occur due to the false recognition of the pin state as an input signal
become possible.
5. Clock signals
After applying a reset, only release the reset line after the operating clock signal becomes stable. When switching the clock signal during program
execution, wait until the target clock signal is stabilized. When the clock signal is generated with an external resonator or from an external oscillator
during a reset, ensure that the reset line is only released after full stabilization of the clock signal. Additionally, when switching to a clock signal
produced with an external resonator or by an external oscillator while program execution is in progress, wait until the target clock signal is stable.
6. Voltage application waveform at input pin
Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the CMOS device stays in the area between V
(Max.) and V
input level is fixed, and also in the transition period when the input level passes through the area between V
7. Prohibition of access to reserved addresses
Access to reserved addresses is prohibited. The reserved addresses are provided for possible future expansion of functions. Do not access these
addresses as the correct operation of the LSI is not guaranteed.
8. Differences between products
Before changing from one product to another, for example to a product with a different part number, confirm that the change will not lead to problems.
The characteristics of a microprocessing unit or microcontroller unit products in the same group but having a different part number might differ in terms
of internal memory capacity, layout pattern, and other factors, which can affect the ranges of electrical characteristics, such as characteristic values,
operating margins, immunity to noise, and amount of radiated noise. When changing to a product with a different part number, implement a systemevaluation test for the given product.
(Min.) due to noise, for example, the device may malfunction. Take care to prevent chattering noise from entering the device when the
