Section 3 MCU Operating Modes
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, 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 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. These pins can be set to output
addresses by setting the corresponding bits to 1 in pin function control register 1 (PFCR1) in the
case of ports A and B, or in the data direction register (DDR) for port C. 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 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.
3.3.7
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.
3.3.8
Modes 8 and 9 are not supported and must not be set.
3.3.9
This is a flash memory boot mode. For details, see section 19, ROM.
Except for the fact that flash memory programming and erasing can be performed, operation in
this mode is the same as in advanced expanded mode with on-chip ROM enabled.
