Relationship between the RESET Input and the Phase Current and MO Outputs
Example 1: 1-2-phase excitation (M1: H, M2: L)
Setting the RESET signal Low causes the outputs to be put in the Initial state and the MO output to be
Low. (Initial state: A-channel output current is at its peak (100%).) When the RESET signal goes High again,
the output current generation is resumed at the next rising edge of the CK signal with the state following the
Initial state. If RESET goes High when CK is already High, the output current generation is resumed
immediately without waiting for the next rising edge of CK with the state following the Initial state.
Example 2: 2W12 phase excitation (M1: H, M2: H)
