The test parameter is selected by bits D0 to D6. There are two EXT pins. EXT

The meanings of the symbols listed in Table 7 are as follows:
Power save mode sets by D7 bit.
When power save mode is selected, circuit consumption current can be reduced. Detail of power save function is
The 5th byte sets the enable, rotation, and output current of
The enable sets by bit D7, the rotation sets by bit D6, and the output current sets by bits D0 to D4. Bit D5 is fixed
