Section 3 MCU Operating Modes
3.1 MCU Operating Mode Selection
This LSI has two operating modes (modes 2 and 3). The operating mode is determined by the
setting of the mode pins (MD1 and MD0). Table 3.1 shows the MCU operating mode selection.
Table 3.1 lists the MCU operating modes.

Modes 2 and 3 set the operation in single-chip mode.
Modes 0 and 1 cannot be used in this LSI. Thus, mode pins should be set to enable mode 2 or 3 in
normal program execution state. Mode pins should not be changed during operation.
