microcomputer. A software reset has the same effect as a hardware reset. The contents of internal RAM
are preserved.
(1) Types of Processor Mode
(2) Setting Processor Modes
One of three processor modes can be selected: single-chip mode, memory expansion mode, and micro-
processor mode. The functions of some pins, the memory map, and the access space differ according to
the selected processor mode.
The processor mode is set using the CNV

Regardless of the level of the CNV
never change the processor mode bits when changing the contents of other bits. Do not change the
processor mode bits simultaneously with other bits when changing the processor mode bits “01

In single-chip mode, only internal memory space (SFR, internal RAM, and internal ROM) can be
accessed. However, after the reset has been released and the operation of shifting from the micropro-
cessor mode has started (“H” applied to the CNV
even if the CPU shifts to the single-chip mode.
Ports P0 to P10 can be used as programmable I/O ports or as I/O ports for the internal peripheral
functions.
In memory expansion mode, external memory can be accessed in addition to the internal memory
space (SFR, internal RAM, and internal ROM). However, after the reset has been released and the
operation of shifting from the microprocessor mode has started (“H” applied to the CNV
internal ROM area cannot be accessed even if the CPU shifts to the memory expansion mode.
In this mode, some of the pins function as the address bus, the data bus, and as control signals. The
number of pins assigned to these functions depends on the bus and register settings. (See “Bus
Settings” for details.)
In microprocessor mode, the SFR, internal RAM, and external memory space can be accessed. The
internal ROM area cannot be accessed.
In this mode, some of the pins function as the address bus, the data bus, and as control signals. The
number of pins assigned to these functions depends on the bus width and register settings. (See “Bus
Settings” for details.)
The microcomputer begins operation in single-chip mode after being reset. Memory expansion mode
is selected by writing “01
