... Timer Mode – The transition of pin 1 (TSTART) from a high to low level initiates a ten minute timer. During this 10 minute period the open drain NMOS on pin 4 (TSTROBE) is strobed on with the internal clock. A resistor connected to this pin could be used to modify the detector sensitivity for the timer period. © 2009 Microchip Technology Inc. R&E International A Subsidiary of Microchip Technology Inc.
