[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 593,468, filed February 1, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to an input capture peripheral unit. Background technique [0004] A microcontroller includes a microprocessor, memory, and multiple peripherals all integrated into a single chip. Many microcontrollers are so highly integrated that they do not require any external components. Consequently, many of the integrated peripherals can be very complex in design and function. The input capture peripheral is operable to read the timer upon internal or external trigger. Thus, input capture peripherals are typically used within microcontrollers to measure time, provide pulse width modulation functionality, and the like. In noisy environments, using a capture peripheral may not be feasible due to the fact that the unit...
