timer concept

I.m using MTU (multifunction timer unit).In that i want to know what is mean by compare match and input capture.Thanks .

  • Hello Priya,

    The input capture is acquisition of a signal by the timer for event time or count mode. The Capture Match is then used to match the counter value to a known value and generate an user interrupt.

  • Thanks a lot.what is meant by timer i/o control in multi function timer unit.
    here i have mentioned one example.
    0 0 0 0 Output compare register Output prohibited0 0 0 1 Initial output is low.
    Low output at compare match.0 0 1 0 Initial output is low.
    High output at compare match.0 0 1 1 Initial output is low.
    Toggle output at compare match.0 1 0 0 Output prohibited
    0 1 0 1 Initial output is high.Low output at compare match.
    0 1 1 0 Initial output is high.High output at compare match.
    0 1 1 1 Initial output is high.Toggle output at compare match.
    1 0 0 0 Input capture register Input capture at rising edge.
    1 0 0 1 Input capture at falling edge.1 0 1 x Input capture at both edges.
    1 1 x x Capture input source is count clock in MTU1.
    Input capture at MTU1.TCNT up-count/down-count.
  • Hello Priya,

    Where is this data coming from? I haven't seen (or atleast not realized) this data in TM4C12x datasheets
