6 / 11 page STK672-050 No. 5228—6/11 2-3. RETURN (It forcibly returns the phase to the origin of current excitation phase.) 1. Pin format sCMOS Schmitt configuration containing pull-up resistor (20k Ω, typical value) 2. Noise eliminating circuit is contained. 3. Function sForces to moves to the origin of current excitation phase by setting the RETURN signal to high state. 2-4. ENABLE(ON/OFF control of excitation drive output A, A, B, and B and selection of operation/hold state in hybrid-IC) 1. Pin format sCMOS Schmitt configuration containing pull-up resistor (20 k Ω, typical value) 2. Function a. When the ENABLE signal is set to a high state or it is opened. It is usually placed in the operation status. b. When the ENABLE signal is set to a low state The hybrid-IC is placed into the hold state, forcing the excitation drive output to be turned off. At this time, the system clock of the HC stops, the H-IC is not affected if the input pin other than the reset input changes. 2-5. M1, M2, and M3 (Selection of excitation modes and clock input edge timing) 1. Pin format sCMOS Schmitt configuration containing the pull-up resistor (20 k Ω typical value) 2. Functions 3. Valid timing of mode setting sThe mode must not be changed within 5 µs from the rising edge and falling edge of the clock.
