3.3
3.3.1
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is disabled.
Ports 1, 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 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 1, A, B, and C function as an address bus, port D 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 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 1, 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 initial bus mode 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.
