Alternatively, it can measure a pulse width using a known clock rate, or a frequency, by counting input pulses over a known time interval. It includes one 16-bit or 24bit counter which may also be used separately (PE12016G only). The PE12016G may be cascaded to provide accuracy greater than 16bits. Both devices are designed for use in many microprocessor-ba...
