Section 3 MCU Operating Modes
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.
3.2
The following registers are related to the operating mode setting.
• Mode control register (MDCR)
• System control register (SYSCR)
3.2.1
MDCR indicates the current operating mode. When MDCR is read from, the states of signals
MD2 to MD0 are latched. Latching is released by a reset.
