MEMORY
• Special Function Register (SFR) Area
The Special Function Register area in the zero page contains
control registers such as I/O ports and timers.
• RAM
The RAM is used for data storage and for stack area of
subroutine calls and interrupts.
• ROM
The first 128 bytes and the last 2 bytes of ROM are reserved for
device testing and the rest is a user area for storing programs. In
the QzROM version, 1 byte of address FFDB
area.
• Interrupt Vector Area
The interrupt vector area contains reset and interrupt vectors.
• 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.

• ROM Code Protect Address (address FFDB
Address FFDB
the ROM code protect address. “00
this address when selecting the protect bit write by using a serial
programmer or selecting protect enabled for writing shipment by
Renesas Technology corp. When “00
ROM code protect address, the protect function is enabled, so
that reading 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
programmer.
The protect can be performed, dividing twice. The protect area 1
is from the beginning address of ROM to address “EFFF
for the QzROM product shipped after writing, “00
enabled to all area), “FE
or “FF

<Notes>
Since the contents of RAM are undefined at reset, be sure to set
an initial value before use.
