Connect the CNV
pattern which is supplied to the V
In addition connecting an approximately 5 kΩ 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.
• Reason
The CNV
QzROM. When programming in the QzROM, the impedance of
the V
into the built-in QzROM. Because of this, noise can enter easily.
If noise enters the V
are read from the QzROM, which may cause a program runaway.

Notes On QzROM Writing Orders
When ordering the QzROM product shipped after writing,
submit the mask file (extension: .mask) which is made by the
mask file converter MM.
Be sure to set the ROM option (“MASK option” written in the
mask file converter) setup when making the mask file by using
the mask file converter MM.

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 mask option setup data in the
mask file which is submitted at ordering.
Renesas Technology corp. uses the mask option setup data at the
ROM code protect address (address FFDB
QzROM. Consequently, the actual written value might differ
from the ordered value as the contents of the ROM code protect
address.
The ROM option setup data in the mask file is “00
enabled, “FE
“FF
code protect address of the QzROM product shipped after
writing are “00
Note that the mask file which has nothing at the ROM option
data or has the data other than “00
be accepted.
DATA REQUIRED FOR QzROM WRITING ORDERS
The following are necessary when ordering a QzROM product
shipped after writing:
1. QzROM Writing Confirmation Form*
2. Mark Specification Form*
3. ROM data...........Mask file
* For the QzROM writing confirmation form and the mark
specification form, refer to the “Renesas Technology Corp.”
