Are there internal pull-up resistors on the Enhanced Mini-ACE™’s digital inputs?

A. Yes. There are pull-up resistors on all of the inputs and I/O, except for the clock input. More accurately, these are current sources from VCC, with the current value in the range from 50 to 350 µA. In addition, there are Schmidt triggers on all digital input signals (including I/Os), including the clock input. CLK_IN is a CMOS type input. Its VIlis 0.2•VCCmax, its VIHis 0.8•VCCmin, and the minimum Schmidt hysterisis window is 1 volt. The other inputs are TTL type, with VIl= 0.7V max, VIH= 2.1V min, and a minimum Schmidt hysterisis window of 0.4V. Enhanced Mini-ACE™: BC ModeQ. For the Enhanced Mini-ACE™, are there any “rollover” enforcement for the op-code instruction list? Same question for the Command/Status blocks.A. There are no rollover enforcements for the Enhanced Mini-ACE™’s BC op code instruction list or for the Command/Status blocks.
