OPERATION - PUSHBUTTON RESET

continue to monitor the line looking for a rising edge. Upon detecting a release, the DS1233 will force the

RST

line low and hold it low for 350 ms.

NOTE:

For proper operation with an external pushbutton, a capacitor between 100 pF and 0.01

µF must be

minimum capacitance of 500 pF should be used, along with a parallel external pull-up resistor of 1

k

Ω=minimum.
