RESET

This pin will fall low after the VCC’s falling below the reset threshold voltage and

it also can remain asserted for at least 140ms min after VCC’s rising upon the

reset threshold.

Input of manual reset. A reset can be forced by a logic low on MR . As the MR

is held low, the reset will remain asserted, and until the MR rise high, the

reset will remain 140ms min at least. When it is float that means it is unused.

VCC

Input of power supply.
