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 valid.
Immediately after a reset, ports A, B, and C become input ports. The AE3 to AEO bits in PFCR
allow enable/disable setting of the address (A23 to A8) output, regardless of the corresponding
DDR value. The pin which is disabled of the address output at ports A and B becomes an output
port when the corresponding DDR is set to 1.
The address (A7 to A0) is output when the corresponding DDR is set to 1 at port C.
Ports D and E are data buses, and a part of the port F is the bus control signal.
Immediately after a reset, 8-bits bus mode is set and all the areas become 8-bit access space.
However, when any of the areas is set to 16-bit access space by the bus controller, 16-bit bus
mode is set and port E becomes the data bus.
3.3.2
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is valid and
the external address space cannot be accessed.
All the I/O port can be used as an input/output port.
3.3.3
Table 3.2 shows the pin functions in modes 6 and 7.
