Note 1: Production testing done at TA = +25°C; limits over temperature guaranteed by design only.
Note 2: The device is powered up by the highest voltage between VBATT and VCC.
Note 3: MR input ignores falling input pulses, which occur within the MR debounce period (tDEB) after a valid MR reset assertion.
This prevents invalid reset assertion due to switch bounce.
