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
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 user area for storing programs.
In the QzROM version, 1 byte of address FFDB16 is also a
reserved 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 FFDB16)
Address FFDB16, which is the reserved ROM area of QzROM, is
the ROM code protect address. “0016” is written into 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 “0016” is set to the 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.
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
ordering.
<Notes>
Since the contents of RAM are undefined at reset, be sure to set
an initial value before use.
