RoboClock offers the user two disable options: HI-Z and HOLD-OFF. The part is disabled by putting the respective bank disable pin, DIS1 or DIS2, into the HIGH state. The disable inputs have an internal pull-down. Once the disable pin (DIS1/DIS2) has been set HIGH, the actual disable state of the output is determined by the OUTPUT_MODE setting. This is shown in Table 3 of the datasheet. When a bank of outputs is disabled to the HI-Z state, the outputs will become high-impedance immediately. An output bank disabled to the HOLD-OFF state will do so after a maximum of 6 output clock cycles from the time the respective disable pin is HIGH. In this state, non-inverting outputs will drive LOW on their falling edge and inverting outputs will drive HIGH on their rising edge. This insures that disabled outputs can be stopped or re-started, at the expected time, without narrow pulses.
