Section 3 MCU Operating Modes
Note that the functions of each pin depend on the operating mode.
The chip can be used only in modes 4 to 7. This means that the mode pins must be set to select one
of these modes. Do not change the inputs at the mode pins during operation.
3.1.2
The chip has a mode control register (MDCR) that indicates the inputs at the mode pins (MD2 to
MD0), and a system control register (SYSCR) that controls the operation of the chip. Table 3-2
summarizes these registers.
