Section 3 MCU Operating Modes
3.3.5
The CPU operating mode is advanced mode in which the address space is 16 Mbytes, and the on-
chip ROM is disabled.
The initial bus width mode immediately after a reset is eight bits, with 8-bit access to all areas.
Ports D, E, and F function as an address bus, port H functions as a data bus, and parts of ports A
and B function as bus control signals. However, if any area is designated as a 16-bit access space
by the bus controller, the bus width mode switches to 16 bits, and ports H and I function as a data
bus.
3.3.6
The CPU operating mode is advanced mode in which the address space is 16 Mbytes, and the on-
chip ROM is enabled.
The initial bus width mode immediately after a reset is eight bits, with 8-bit access to all areas.
Ports D, E, and F function as input ports, but they can be used as an address bus by specifying the
data direction register (DDR) for each port. For details, see section 13, I/O Ports. Port H functions
as a data bus, and parts of ports A and B function as bus control signals. However, if any area is
designated as a 16-bit access space by the bus controller, the bus width mode switches to 16 bits,
and ports H and I function as a data bus.
3.3.7
The CPU operating mode is advanced mode in which the address space is 16 Mbytes, and the on-
chip ROM is enabled.
All I/O ports can be used as general input/output ports. The external address space cannot be
accessed in the initial state, but setting the EXPE bit in the system control register (SYSCR) to 1
enables the external address space. After the external address space is enabled, ports D, E, and F
can be used as an address output bus and ports H and I as a data bus by specifying the data
direction register (DDR) for each port. When the external address space is not in use, ports J and
K can be used by setting the PCJKE bit in the port function control register D (PFCRD) to 1. For
details, see section 13, I/O Ports.
