The DNA/DNR/DNF-CT-601 are a general-purpose counter/timer layer that provides eight independent 32-bit channels, each one having overvoltage protection and optoisolation. They perform up/down counting in a number of flexible modes using values from a Load Register and two Compare Registers. They can act as an event counter, perform width/period measurements and run in quadrature-encode mode where the user sets the direction of the counting.
