Section 3 MCU Operating Modes
3.3
3.3.1
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is disabled.
Ports A, B, and C function as an address bus, ports D and E function as a data bus, and part of port
F carries bus control signals.
The bus mode immediately after a reset is 16 bits, with 16-bit access to all areas. However, note
that if 8-bit access is designated by the bus controller for all areas, the bus mode switches to 8 bits.
3.3.2
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is disabled.
Ports A, B, and C function as an address bus, port D functions as a data bus, and part of port F
carries bus control signals.
The bus mode immediately after a reset is 8 bits, with 8-bit access to all areas. However, note that
if 16-bit access is designated by the bus controller for any area, the bus mode switches to 16 bits
and port E becomes a data bus.
3.3.3
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is enabled.
Ports A, B, and C function as input port pins immediately after a reset. Address output can be
performed by setting the corresponding DDR (data direction register) bits to 1. Port D functions as
a data bus, and part of port F carries bus control signals.
The bus mode immediately after a reset is 8 bits, with 8-bit access to all areas. However, note that
if 16-bit access is designated by the bus controller for any area, the bus mode switches to 16 bits
and port E becomes a data bus.
3.3.4
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is enabled,
but external addresses cannot be accessed. All I/O ports are available for use as input/output ports.
