Notes on QzROM Version
Wiring to OSCSEL pin
(1) OSCSEL = L
Connect the OSCSEL pin the shortest possible to the GND
pattern which is supplied to the V
addition connecting an approximately 5 k Ω resistor in series to
the GND could improve noise immunity. In this case as well as
the above mention, connect the pin the shortest possible to the
GND pattern which is supplied to the V
microcomputer.
(2) OSCSEL = H
Connect the OSCSEL pin the shortest possible to the V
which is supplied to the V
addition connecting an approximately 5 k Ω resistor in series to
the V
the above mention, connect the pin the shortest possible to the
V
microcomputer.
<Reason>
The OSCSEL pin is the power source input pin for the built-in
QzROM.
When programming in the QzROM, the impedance of the
OSCSEL pin is low to allow the electric current for writing to
flow into the built-in QzROM. Because of this, noise can enter
easily. If noise enters the OSCSEL pin, abnormal instruction
codes or data are read from the QzROM, which may cause a
program runaway.

Overvoltage in QzROM Version
Make sure that voltage exceeding the V
applied to other pins. In particular, ensure that the state indicated
by bold lines in figure below does not occur for pin OSCSEL pin

QzROM Version 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 approximate
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.
Ordering QzROM Writing
1. Notes On QzROM Writing Orders
When ordering the QzROM product shipped after writing,
submit the mask file (extension: .msk) which is made by the
mask file converter MM.
• Be sure to set the ROM option data* setup when making the
• Set “FF
* ROM option data: mask option noted in MM
2. Data Required for QzROM Ordering
The following are necessary when ordering a QzROM product
shipped after writing:
* For the QzROM writing confirmation form and the mark
specification form, refer to the “Renesas Technology Corp.”
Homepage (http://www.renesas.com/homepage.jsp).
Note that we cannot deal with special font marking (customer's
trademark etc.) in QzROM microcomputer.
3. QzROM Product Receiving Procedure
When writing to QzROM is performed by user side, the
receiving inspection by the following flow is necessary.
