use of brown-out reset (BOR)
I'm currently working on a battery powered system using MCU PIC24FJ64GA702. This MCU has a default BOR threshold voltage of ~ 2.1 V. Due to the design of my system + the characteristics of the battery, during the system operation the voltage will have a drop of about 0.1 V for a very short period of time. For example, when the voltage of the battery decreased to 2.2 V, the voltage of system will drop to 2.1 V for a very short period and trigger the BOR.
I don't understand the purpose of having the BOR, could someone please explain me that?
If I disable the BOR, I will not hit the BOR and therefore have a longer life of the system using the battery, is there going to be problem because of that?
What can I do with the BOR flag?
