In the flash memory version, user program mode is entered by setting the SWE bit of FLMCR1 to
1.
3.3.5 Mode 5
This mode is a user boot mode of the flash memory. This mode is the same as mode 7, except for
the programming and erasure on the flash memory. Mode 5 is only available in the H8S/2368 0.18
μm F-ZTAT Group.
3.3.6 Mode 7
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is enabled,
and the chip starts up in single-chip mode. External address space cannot be used in single-chip
mode.
The initial mode after a reset is single-chip mode, with all I/O ports available for use as
input/output ports. However, the mode can be switched to externally expanded mode by setting 1
to the EXPE bit of SYSCR and then the external address space is enabled. When externally
expanded mode is selected, all areas are initially designated as 16-bit access space. The functions
of pins in ports A to G are the same as in externally expanded mode with on-chip ROM enabled.
In the flash memory version, user program mode is entered by setting the SWE bit of FLMCR1 to
1.
