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.

3. Description of Registers
Each register description includes a bit chart, illustrating the arrangement of bits, and a table of
bits, describing the meanings of the bit settings. The standard format and notation for bit charts
and tables are described below.
[Table of Bits]

Description
Reserved
These bits are always read as 0.
ASID2 to All 0
ASID0
R/W Address Identifier
These bits enable or disable the pin function.
0 R Reserved
This bit is always read as 0.
1 R Reserved
This bit is always read as 1.
0
Note: The bit names and sentences in the above figure are examples, and have nothing to do with the contents of this
manual.
(1) Bit
Indicates the bit number or numbers.
In the case of a 32-bit register, the bits are arranged in order from 31 to 0. In the case
of a 16-bit register, the bits are arranged in order from 15 to 0.
(2) Bit name
Indicates the name of the bit or bit field.
When the number of bits has to be clearly indicated in the field, appropriate notation is
included (e.g., ASID[3:0]).
A reserved bit is indicated by "".
Certain kinds of bits, such as those of timer counters, are not assigned bit names. In such
cases, the entry under Bit Name is blank.
(3) Initial value
Indicates the value of each bit immediately after a power-on reset, i.e., the initial value.
0: The initial value is 0
1: The initial value is 1
: The initial value is undefined
(4) R/W
For each bit and bit field, this entry indicates whether the bit or field is readable or writable,
or both writing to and reading from the bit or field are impossible.
The notation is as follows:
R/W: The bit or field is readable and writable.
R/(W): The bit or field is readable and writable.
However, writing is only performed to flag clearing.
R: The bit or field is readable.
"R" is indicated for all reserved bits. When writing to the register, write
the value under Initial Value in the bit chart to reserved bits or fields.
W: The bit or field is writable.
(5) Description
Describes the function of the bit or field and specifies the values for writing.
