Description

Ground

Active LOW reset. RESET is asserted if VCC falls below the reset thresh-

old and remains low for at least 140ms after VCC rises above the reset

threshold.

Active HIGH reset. RESET is asserted if VCC falls below the reset thresh-

old and remains high for at least 140ms after VCC rises above the reset

threshold.
