Store/Wait/Resume Stop Counting Store Count Resume Counting Store Count Mode 3: Store-Reset/Wait/Start In mode 3, the rising edge of a pulse input on the Z Gate/Reset terminal will stop counting, read and store the current counter value in the Stored/Accumulated Count word, and reset the counter to zero. The counter does not count while the input pulse on the Z Gate/Reset terminal is high. Counting resumes from zero on the falling edge of the pulse at the Gate/Reset terminal. The stored count information will remain until it is overwritten with new data.
