Section 3 MCU Operating Modes
3.3
3.3.1
This is the user boot mode for the flash memory. The LSI operates in the same way as in mode 7
except for programming and erasing of the flash memory. For details, refer to section 18, Flash
Memory (0.18-µm F-ZTAT Version).
3.3.2
This is the boot mode for the flash memory. The LSI operates in the same way as in mode 7
except for programming and erasing of the flash memory. For details, refer to section 18, Flash
Memory (0.18-µm F-ZTAT Version).
3.3.3
The CPU operating mode is advanced mode in which the address space is 16 Mbytes, and the on-
chip ROM is disabled.
The initial bus width mode immediately after a reset is 16 bits, with 16-bit access to all areas.
Ports D, E, and F function as an address bus, ports H and I function as a data bus, and parts of
ports A and B function as bus control signals. However, if all areas are designated as an 8-bit
access space by the bus controller, the bus mode switches to eight bits, and only port H functions
as a data bus.
3.3.4
The CPU operating mode is advanced mode in which the address space is 16 Mbytes, and the on-
chip ROM is disabled.
The initial bus width mode immediately after a reset is eight bits, with 8-bit access to all areas.
Ports D, E, and F function as an address bus, port H functions as a data bus, and parts of ports A
and B function as bus control signals. However, if any area is designated as a 16-bit access space
by the bus controller, the bus width mode switches to 16 bits, and ports H and I function as a data
bus.
