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
In the QzROM version, the first 128 Kbytes and the last 2 bytes
are reserved for device testing and the rest is the user area. Also,
1 byte of address FFDB16 is reserved.
In the flash memory version, programming and erase operations
can be performed to reserved ROM areas.
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 in QzROM Version (Address
FFDB16)
Address FFDB16 as reserved ROM area in the QzROM version
is ROM code protect address. “0016” or “FE16” is written into
this address when selecting the protect bit write by using a serial
programmer and selecting protect enabled for writing shipment
by Renesas Technology Corp. When “0016” or “FE16” is set to
the ROM code protect address, the protect function is enabled, so
that reading or writing from/to the corresponding area 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 “EFFF16”.
As for the QzROM product shipped after writing, “0016” (protect
enabled to all area), “FE16” (protect enabled to the protect area 1)
or “FF16” (protect disabled) is written into the ROM code protect
address when Renesas Technology Corp. performs writing. The
writing of “0016”, “FE16” or “FF16” can be selected as ROM
option setup (“MASK option” written in the mask file converter)
when ordering.
For the ROM code protect in the flash memory version, refer to
the “FLASH MEMORY MODE”.
<Notes>
After a reset, the contents of RAM are undefined. Make sure to
set the initial value before use.
When Renesas ships QzROM write products, we write ROM
option data* specified by the mask file converter MM to the
ROM code protect address. Therefore, set FF16 to the ROM
code protect address in ROM data regardless of the presence
or absence of a protect. When data other than FF16 is set, we
may ask that the ROM data be submitted again.
* ROM option data: mask option noted in MM
