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  
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  
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 may  
occur due to the false recognition of the pin state as an input signal. 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 one with a different part number, confirm  
that the change will not lead to problems.  
⎯ 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.
