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 disabled.
Ports A to C function as an address bus, ports D and E function as a data bus, and parts of ports F
to H function as bus control signals.
The initial bus mode immediately after a reset is 16 bits, with 16-bit access to all areas. However,
if 8-bit access is designated for all areas by the bus controller, 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 A to C function as an address bus, ports D and E function as a data bus, and parts of ports F
to H function as bus control signals.
The initial bus mode immediately after a reset is 8 bits, with 8-bit access to all areas. However, if
16-bit access is designated for any one of the areas by the bus controller, the bus mode switches to
16 bits and port E functions as a data bus.
3.3.3
This mode is a boot mode of the flash memory. This mode is the same as mode 7, except for the
programming and erasure of the flash memory. Mode 3 is only available in the flash memory
version.
