3.1.2 Notes on ADC16 Configuration
To display the ADC16 conversion results using QE for AFE, please increase the number of enabled
channels and set the sampling time longer (see Figure 3-2). If LED1 on the evaluation board is always on,
which means the board is not operating properly, please restart QE for AFE and reset the sample project to
try again.
Figure 3-2 ADC16 configuration setting
3.1.3 Notes on “stop AFE tuning” Operation Failure
Occasionally user click “stop AFE tuning” button on [AD Monitor] tab but the tuning doesn’t stop. As a
workaround of this case, please click “Disconnect” button to disconnect QE for AFE with evaluation board.
Then click “Connect” button after resetting the evaluation board.
3.1.4 Notes on Setting DAC8/DAC12 Output Pin Function
QE for AFE V1.0.0 doesn’t support to set PmnPFS register which is used to set DAC8/DAC12 output pin
function. Please set PmnPFS register in firmware program manually when you need to use DAC8/DAC12
output pin.
3.1.5 Notes on Tuning Time on [AD Monitor] Tab
When tuning on [AD Monitor] tab, QE for AFE obtains A/D conversion values from the evaluation board. If
the tuning time is very long, too much data will lead to the host PC memory overflow. So, QE for AFE V1.0.0
supports tuning time no more than 1 hour. If tuning operates for more than 1 hour, the tool will stop tuning
automatically and output a message to inform user that the tuning time can’t exceed 1 hour.
Enable more channels
Set the sampling time longer

3.1.6 Notes on Tuning ADC16 on [AD Monitor] Tab
Please note the follow procedure by which QE for AFE get ADC16 conversion result from the evaluation
board:
1) After user click “Start AFE tuning” button on [AD Monitor] Tab in QE for AFE, ADC16 starts conversion
on evaluation board.
2) On evaluation board, when the A/D conversion result buffer is full, the sample project stops ADC16
conversion and send response to QE for AFE.
3) QE for AFE starts to read data from evaluation board until the result buffer is empty.
4) QE for AFE restart ADC16 conversion, the procedure goes to 2)
Above 2) to 4) is internal communication between QE for AFE and sample project, which will continue until
user click “stop AFE tuning” button.
3.1.7 Notes on UART connection
Please note the following items when using UART connection.
1) After reset of the evaluation board, please set bitrate as 1000000bps in the [ConnectSetting] dialog, then
click “connect” button.

2) After successful connection with evaluation board, you can open the [ConnectSetting] dialog to change
the bitrate setting. 1000000bps, 1500000bps, 2000000bps, or 3000000bps can be input manually or
selected from the combo box.
3) It's rare case that the current bitrate information displayed in [ConnectSetting] dialog is invalid. When
you met this case, please confirm the message output in [Console] window firstly. If the message is
“[Info]Set bitrate successfully”, the invalid information can be ignored. If bitrate change failed, please try
it again.

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 VIL
(Max.) and VIH (Min.) due to noise, for example, the device may malfunction. Take care to prevent chattering noise from entering the device when the
input level is fixed, and also in the transition period when the input level passes through the area between VIL (Max.) and VIH (Min.).
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.
