6. ENA pin function and I
2C serial data output enable setting
[ENA pin]
VCC consumption current during standby can be reduced to virtually zero by setting the ENA input pin to low.
Furthermore, when this pin is set to low, the output becomes OFF state (high-impedance), and the state of the internal
logic circuit is set to the initial excitation position (initial position).
By setting the ENA pin to high, the output becomes ON state, and the circuit operates from the initial excitation position.
* The output does not operate unless “output enable” is set to the “output ON” state using an I2C serial data
communication.
[I2C serial data output enable setting]
When “output enable” is set to the “output OFF” state, the output is placed in the high-impedance state at the rising edge
of the 8th SCL bit in the data transmission.
However, since the internal logic circuit is activated, the position number advances if CLK has been input. This means
that when “output enable” is set to the “output ON” state after this, the output is set to ON at the rising edge of the 8th
SCL bit in the data transmission, and that the output level at this time will be the level at the number to which the position
has advanced by the CLK input.
