Manual reset input. A logic low on MR asserts reset. Reset remains asserted as
long as MR is low and for at least 140ms after MR returns high, This active-low
input has an internal 20kΩ pull-up resistor. It can be driven from a TTL or
CMOS-logic line, or shorted to ground with a switch. Leave open if unused.
