    A signal source without a local ground is also called a “floating source”. It is fairly simple to connect a single-ended channel to a floating signal source. In this mode, the MIC-3716 provides a reference ground for external floating signal sources. Fig. 3-2 shows a single-ended channel connection between a floating signal source and an input channel on the MIC-3716.

That is if we set the AI0 and AI1 as a differential input channel, we can get the correct result no matter if we poll channel 0 or channel 1.
  • Page 95 Warning! Only even channels can be set as differential. An odd channel will become unavailable if its preceding channel is set as differential.

  • Page 115: Counter Operating Modes

    D.3 Counter Operating Modes MODE 0 – Stop on Terminal Count The output will initially be low after you set this mode of operation. After you load the count into the selected count register, the output will remain low and the counter will count. When the counter reaches the terminal count, its output will go high and remain high until you reload it with the mode or a new count value.
  • Page 116 pulses, the present period will not be affected, but the subsequent period will reflect the value. The gate input, when low, will force the output high. When the gate input goes high, the counter will start from the initial count. You can thus use the gate input to synchronize the counter.
  • Page 117 (N+1)/2 counts and low for (N-1)/2 counts. MODE 4 –Software-Triggered Strobe After the mode is set, the output will be high. When the count is loaded, the counter will begin counting. On terminal count, the output will go low for one input clock period then go high again. If you reload the count register during counting, the new count will be loaded on the next CLK pulse.

  • Page 118: Counter Operations

    D.4 Counter Operations Read/Write Operation Before you write the initial count to each counter, you must first specify the read/write operation type, operating mode and counter type in the control byte and write the control byte to the control register [BASE + 30(Dec)].
  • Page 119 latch commands, one for each counter latched. The read-back command can also latch status information for selected counter(s) by setting STA bit = 0. The status must be latched to be read; the status of a counter is accessed by a read from that counter. The counter status format appears at the beginning of the chapter.
