1.11 MEMORY MAP
The first 112 bytes of memory from 000016 to 006F16
is the special function register (SFR) area and con-
tains the CPU mode registers, interrupt registers, and
other registers to control peripheral functions (see
Figure 1.7).
The general purpose RAM resides from 007016 to
046F16. When the MCU is in memory expansion or
microprocessor mode and external memory is over-
laid on the internal RAM, the CPU reads data from
the internal RAM. However, the CPU writes data in
both the internal and external memory. The area from
047016 to 7FFF16 is not used in single-chip mode, but
can be mapped for an external memory device when
the MCU is in memory expansion or microprocessor
mode.
The area from 800016 to 807F16 and from FFFC16 to
FFFF16 are factory reserved areas. Mitsubishi uses it
for test and evaluation purposes. The user can not
use this area in single-chip or memory expansion
modes.
The user 32K byte ROM resides from 808016 to
FFFB16. When the MCU is in microprocessor mode,
the CPU accesses an external area rather than ac-
cessing the internal ROM.
1.11.1 Special page
The 256 bytes from address FF0016 to FFFF16 are
called the special page area. In this area special page
addressing can be used to specify memory ad-
dresses. This dedicated special page addressing
mode enables access to this area with fewer instruc-
tion cycles. Frequently used subroutines are normally
stored in this area.
