Section 3 MCU Operating Modes
The initial bus mode 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.
3.3.5
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 initial bus mode after a reset is 8 bits, with 8-bit access to all areas. However, note that if at
least one area is designated for 16-bit access by the bus controller, the bus mode switches to 16
bits and port E becomes a data bus.
3.3.6
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 ports immediately after a reset. They can each be set to output
addresses by setting the corresponding bits in the data direction register (DDR) to 1. Port D
functions as a data bus, and part of port F carries bus control signals.
The initial bus mode after a reset is 8 bits, with 8-bit access to all areas.
3.3.7
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.
