Section 3 Operating Modes
3. Operating Modes
3.1 Operating Modes, Types, and Selection
This LSI has five operating modes and three clock modes, determined by the setting of the mode
pins (MD3 to MD0). Do not change the mode pin settings during LSI operation (while power is
on).
Table 3.1 indicates the setting method for the operating mode.
