About pulse width detected by LVD circuit

Last Updated:01/16/2018

Question:

Per the LVD circuit characteristics, the specified minimum pulse width that can be detected is 300 μs. How will the MCU operate when the detection voltage falls below the value specified by the option byte for less than 300 μs due to external noise or other factors?

Answer:

Since it is less than the minimum pulse width specified per the electrical characteristics, there is no guarantee that the low voltage condition will be detected.
Therefore, the MCU may be reset or an interrupt may be generated, or neither of them may occur.
