Example 2: Switching from 1-2 phase to 2-phase excitation

Motor status is maintained when the excitation mode (MODE) is switched during motor rotation.

Because CLOCK cannot be detected when the interval between the rise in the MODE signal and CLOCK signal is 5μs

or less, the mode may not change for one CLOCK cycle.
