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 manual, refer to the relevant sections of the manual. If the descriptions under
General Precautions in the Handling of MPU/MCU Products and in the body of the manual differ from each
other, the description in the body of the manual takes precedence.
1. Handling of Unused Pins
2. Processing at Power-on
3. Prohibition of Access to Reserved Addresses
4. Clock Signals
5. Differences between Products
Handle unused pins in accord 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
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
Access to reserved addresses is prohibited.
 The reserved addresses are provided for the possible future expansion of functions. Do
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

that the change will not lead to problems.

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

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.

accessed.
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.
The characteristics of MPU/MCU in the same group but having different part numbers may
differ because of the differences in internal memory capacity and layout pattern. When
changing to products of different part numbers, implement a system-evaluation test for
each of the products.
