3.3
3.3.1
Mode 1 is not supported in this LSI, and must not be set.
3.3.2
This is a flash memory boot mode. For details, see section 19, ROM.
MCU operation is the same as in mode 6.
3.3.3
This is a flash memory boot mode. For details, see section 19, ROM.
MCU operation is the same as in mode 7.
3.3.4
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 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. 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.
