3.1
This LSI has five operating modes (modes 2, 4, 5, 6, and 7). The operating mode is selected by the
setting of mode pins (MD2 to MD0). Table 3.1 lists MCU operating mode settings.
Table 3.1
In this LSI, an advanced mode as the CPU operating mode and a 16-Mbyte address space are
available. The initial external bus widths are eight or 16 bits. As the LSI initiation mode, the
external extended mode, on-chip ROM initiation mode, or single-chip initiation mode can be
selected.
Mode 2 is the boot mode in which the flash memory can be programmed and erased. For details
on the boot mode, see section 20, Flash Memory (0.18-µm F-ZTAT Version).
Mode 7 is a single-chip initiation mode. In the initial state, all areas are designated to 8-bit access
space and 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 to use 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.
Modes 4 to 6 are external extended modes, in which the external memory and devices can be
accessed. In the external extended modes, the external address space can be designated as 8-bit or
16-bit address space for each area by the bus controller after starting program execution.
If 16-bit address space is designated for any one area, it is called the 16-bit bus widths mode. If 8-
bit address space is designated for all areas, it is called the 8-bit bus width mode.
