In Mode 7, Ua1 carries the signal of unknown frequency to be measured, and Ua2 is a gate signal of known width. A low to high transition of the Ua2 signal enables counting at the frequency of Ua1. When the gate Ua2 goes low, counting is disabled, the value is stored again in the Channel Counter Output Register, and the counter is cleared.
