However, they can be programmed or erased in the flash
memory version, so that the users can use them.

MEMORY
RAM
RAM is used for data storage and for stack area of subroutine
calls and interrupts.
ROM
ROM is used for program code and data table storage.
The first 128 bytes and the last 2 bytes of ROM are reserved for
device testing code and the rest is user area.
Zero Page
Access to this area with only 2 bytes is possible in the zero page
addressing mode.
Special Page
Access to this area with only 2 bytes is possible in the special
page addressing mode.
Interrupt Vector Area
The interrupt vector area contains reset and interrupt vectors.
Special Function Register (SFR) Area
The special function register area contains the control registers
such as I/O ports, timers, serial I/O, etc.
ROM Code Protect Address
“0016 ” is written into ROM code protect address (other than the
user ROM area) when selecting the protect bit write by using a se-
rial programmer or selecting protect enabled for writing shipment
by Renesas Technology corp..When “0016 ” is set to the ROM
code protect address,the protect function is enabled,so that read-
ing or writing from/to QzROM is disabled by a serial programmer.
As for the QzROM product in blank, the ROM code is protected by
selecting the protect bit write at ROM writing with a serial pro-
grammer.
As for the QzROM product shipped after writing,“0016 ” (protect
enabled) or “FF16 ” (protect disabled) is written into the ROM code
protect address when Renesas Technology corp. performs writing.
The writing of “0016" or “FF16 ” can be selected as ROM option
setup (“MASK option ” written in the mask file converter) when or-
dering.
