Section 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–MD0). Do not change the mode pin settings during LSI operation (while power is on).
(In the F-ZTAT version, however, MD1 can be changed in the power-on reset state.)
Table 3.1 indicates the setting method for the operating mode.
