Reset
Power-on reset
Under the following condition, the system reset occurs by the
built-in the power-on reset circuit of this product;
-
when the supply voltage (VDD) rises from 0 V to 2.2 V, within
1 ms.
Also, note that system reset does not occur under the
following conditions;
-
when the supply voltage (VDD) rises from the voltage higher
than 0V, or
-
when it takes more than 1 ms for the supply voltage (VDD)
to rise from 0 V to 2.2 V.
⑨ Voltage drop detection circuit
The voltage drop detection circuit detection voltage of this
product is set up lower than the minimum value of the supply
voltage of the recommended operating conditions.
A battery exchange of an application product is explained as
an example.
The supply voltage falls below to the recommended operating
voltage while CPU keeps active. Then, an unexpected
oscillation-stop, which does not happen by POF instruction
occurs before the supply voltage falls below to the detection
voltage. In this time, even if the supply voltage re-goes up to
the recommended operating voltage, since reset does not
occur, MCU may not operate correctly.
Please confirm the oscillator you use and the frequency of
system clock, and test the operation of your system sufficiently.
Note on Power Source Voltage
When the power source voltage value of a microcomputer is
less than the value which is indicated as the recommended
operating conditions, the microcomputer does not operate
normally and may perform unstable operation.
In a system where the power source voltage drops slowly when
the power source voltage drops or the power supply is turned
off, reset a microcomputer when the supply voltage is less
than the recommended operating conditions and design a
system not to cause errors to the system by this unstable
operation.

Note on product shipped in blank
As for the product shipped in blank, Renesas does not perform
the writing test to user ROM area after the assembly process
though the QzROM writing test is performed enough before
the assembly process. Therefore, a writing error of approx.
0.1 % may occur.
Moreover, please note the contact of cables and foreign bodies
on a socket, etc. because a writing environment may cause
some writing errors.
QzROM
(1) Be careful not to apply overvoltage to MCU. The contents
of QzROM may be overwritten because of overvoltage.
Take care especially at turning on the power.
(2) As for the product shipped in blank, Renesas does not per-
form the writing test to user ROM area after the assembly
process though the QzROM writing test is performed
enough before the assembly process. Therefore, a writing
error of approx.0.1 % may occur. Moreover, please note
the contact of cables and foreign bodies on a socket, etc.
because a writing environment may cause some writing er-
rors.
Notes On ROM Code Protect
(QzROM product shipped after writing)
As for the QzROM product shipped after writing, the ROM
code protect is specified according to the ROM option setup
data in the mask file which is submitted at ordering.
The ROM option setup data in the mask file is “0016” for pro-
tect enabled or “FF16” for protect disabled.
Note that the mask file which has nothing at the ROM option
data or has the data other than “0016” and “FF16” can not be
accepted.
