3803 Group (Spec.H QzROM version)
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 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” or “FE16” 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” or “FE16” 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.
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.
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.
