Section 3 MCU Operating Modes
Modes 1 and 2 are the user boot mode and the boot mode, respectively, in which the flash memory
can be programmed and erased. For details on the user boot mode and boot mode, see section 25,
Flash Memory.
Mode 3 is the boundary scan function enabled single-chip mode. For details on the boundary scan
function, see section 26, Boundary Scan.
Mode 7 is a single-chip initiation mode. 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. When the external
address space is not in use, ports J and K can be used by setting the PCJKE bit in the port function
control register D (PFCRD) to 1.
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.
