Relationship between the Enable and
Example 1: ENABLE input in 1-2-phase excitation mode (M1: H, M2: L)
output block continues to operate in accordance with the CLK input. Therefore, when the ENABLE signal goes
High again, the output current generation is restarted as if phases proceeded with the CLK signal.
