/MR

Digital (Input): Driving this pin low initiates an immediate and unconditional

reset. Assuming IN is above the threshold when /MR is released (returns

high), the reset output will be de-asserted no less than 140ms later. /MR

may be driven by a logic signal or a mechanical switch. /MR has an internal

IN

Analog (Input): The voltage on this pin is compared to the internal 300mV

reference. An under-voltage condition will trigger a reset sequence.
