2. Board Soldering
To connect the RSK CPU board and the TSA-OP-IC101 board, the user must attach pin sockets or headers to the
extension board interface (herein referred to as “application header”). This section explains the soldering locations on
both boards.
RSK CPU Board
Solder pin sockets to the RSK CPU board application headers (JA1, JA2, JA5, and JA6). Solder 26 pins (2 x 13)
to JA1 and JA2, and 24 pins (2 x 12) to JA5 and JA6, facing upward. Make sure the pin sockets are mounted
perpendicular to the board.

TSA-OP-IC101 Board
Solder pin headers to the application headers (JA1, JA2, JA5, and JA6) on the TSA-OP-IC101 board. Solder the pin
headers facing downward (facing the board), with 26 pins (2 x 13) to JA1 and JA2, and 24 pins (2 x 12) to JA5 and JA6.
Make sure the pin headers are mounted perpendicular to the board.
Although Easy Starter 101 does not use the LCD extension board, if you are using the LCD Extension Board while it is
connected to the TSA-OP-IC101 board, make sure you solder 50 pin headers (2 x 25) to the application header (JA4)
facing downward (facing the board), and 50 pin sockets (2 x 25) to the application header (JA4_COPY1) facing upward.

7.3 Read Setting File
Easy Starter 101 allows the user to reload the stored settings by reading the Setting fileNote stored in the register set
folder. The default register set folder is specified as the setting folder located in the SA_Easy_Starter_101_Ver2.1
folder. To change the register set folder, open the Option Dialog in the Start window and change the folder path in the
Register Set Folder Setting tab.
Note: The Setting file stores information concerning the state of the designed AFE circuit and can be created by the user.
Figure 7-4 Register Set Folder
The TSA-OP-IC101 board is equipped with a thermistor to be used as a sensor to confirm operations. The sensor’s
Setting file required to run the thermistor can be downloaded from the Renesas Electronics website. Store the
downloaded file in the register set folder.
The Setting file will show up in the Register combo box when Easy Starter 101 is started up. If you add the Setting file
while Easy Starter 101 is already running, restart the program to ensure the file is correctly displayed.

After confirming operations as instructed above, confirm the change in waveform by changing the SAIC101 settings.
First, change the value of AIN2OFT in the Chip Config window (sect. 7.3) to 1. This value is used to adjust the offset
voltage. By changing AIN2OFT from 2 to 1, the offset voltage changes from -153.13 / GSET1[mV](GSET1=1) to -164.06 /
GSET1[mV] (GSET1=1).The effect of the changed setting can be confirmed in the ADC Graph window waveform.

7.5 Output AFE Register File
Store the SAIC101 device’s changed AFE register file (sect. 7.4) in an external file. This AFE register file can be
reloaded from the Start window.
The AFE register file contains the following information: register values set in the Chip Config window, A/D
conversion setting values (frequency, number of conversions, channels) set in the Main window frame, and the author,
date created, and description input in the Export window.

First edition issued

General Precautions in the Handling of MPU/MCU Products
The following usage notes are applicable to all MPU/MCU 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. 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 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. Unused pins should be handled as
described under Handling of Unused Pins in the manual.
2. Processing at Power-on
The state of the product is undefined at the moment 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 moment 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 moment 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 moment when power is supplied until the power reaches the level at
which resetting has been specified.
3. Prohibition of Access to Reserved Addresses
Access to reserved addresses is prohibited.
The reserved addresses are provided for the possible future expansion of functions. Do not access
these addresses; the correct operation of LSI is not guaranteed if they are accessed.
4. Clock Signals
After applying a reset, only release the reset line after the operating clock signal has become stable.
When switching the clock signal during program execution, wait until the target clock signal has
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.
Moreover, 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.
5. Differences between Products
Before changing from one product to another, i.e. to a product with a different part number, confirm
that the change will not lead to problems.
The characteristics of an MPU or MCU in the same group but having a different part number may
differ in terms of the 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 system-evaluation test for the given product.
