Section 3 MCU Operating Modes
Mode 5 is an externally expanded mode that enables access to external memory and peripheral
devices and also enables access to the on-chip ROM. Mode 5 supports a maximum address space
of 16 Mbytes.
Modes 6 and 7 are single-chip modes in which the chip operates using only the on-chip ROM,
RAM, and I/O registers. All ports are available in these modes. Mode 6 supports a maximum
address space of 64 kbytes. Mode 7 supports a maximum address space of 1 Mbyte.
The H8/3024 Group can be used only in modes 1 to 7. The inputs at the mode pins must select one
of these seven modes. The inputs at the mode pins must not be changed during operation. Set the
reset state before changing the inputs at these pins.
3.1.2
The H8/3024 Group has a mode control register (MDCR) that indicates the inputs at the mode
pins (MD
