MEMORY
Special Function Register (SFR) Area
The SFR area in the zero page contains control registers such as
I/O ports and timers.
RAM
RAM is used for data storage and for a stack area of subroutine
calls and interrupts. RAM consists of RAM1 and RAM2. The
power source for RAM1 is supplied from VCC pin. The power
source for RAM2 is supplied from VDDR pin.
Note: When the VDDR pin is used, connect an approximately 0.1
F bypass capacitor across the VSS line and the VDDR line.
When not used, connect it to VSS.
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.
Interrupt Vector Area
The interrupt vector area contains reset and interrupt vectors.
Zero Page
The 256 bytes from addresses 000016 to 00FF16 are called the
zero page area. The internal RAM and the special function
registers (SFR) are allocated to this area.
The zero page addressing mode can be used to specify memory
and register addresses in the zero page area. Access to this area
with only 2 bytes is possible in the zero page addressing mode.
Special Page
The 256 bytes from addresses FF0016 to FFFF16 are called the
special page area. The special page addressing mode can be used
to specify memory addresses in the special page area. Access to
this area with only 2 bytes is possible in the special page
addressing mode.
Function Set ROM Area
[Renesas shipment test area]
Figure 10 shows the Assignment of Function set ROM area.
The random data are set to the Renesas shipment test areas
(addresses FFD416 to address FFD916).
Do not rewrite the data of these areas.
When the checksum is included in the user program, avoid
assigning it to these areas.
[Function set ROM data] FSROM
Function set ROM data (address FFDA16) is used to set modes of
peripheral functions. By setting this area, the operation mode of
each peripheral function are set after system is released from
reset.
Refer to the descriptions of peripheral functions for the details of
operation of peripheral functions.
Watchdog timer
Low voltage detection circuit
This mode setting of peripheral functions cannot be changed by
program after system is released from reset.
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 the ROM
option setup (referred to as “Mask option setup” in MM) when
ordering.
<Notes>
1. Because the contents of RAM are indefinite at reset, set ini-
tial values before using.
2. Do not access to the reserved area.
3. Random data is written into the Renesas shipment test area
and the reserved ROM area. Do not rewrite the data in these
areas. Data of these area may be changed without notice.
Accordingly, do not include these areas into programs such
as checksum of all ROM areas.
4. The QzROM values in function set ROM data set the oper-
ating modes of the various peripheral functions after an
MCU reset is released. Do not fail to set the value for the
selected function. Bits designated with a fixed value of 1 or
0 must be set to the designated value.
5. Emulator MCU: As for M37545RLSS, set “010000XX2” to
Function set ROM data (address FFDA16). Also, set “FF16”
to ROM code protect (address FFDB16).
