Amazing contribution it is! So much encouraged me to keep learning
Python. Your this fantastic info is what I wanted to learn and have
it. Thanks again for your sharing. Especailly to me who is very not
familiar with this s/w coding along having long time to learn. But
it's really good experimental example.

Yes, I think you got info from [1]. So a low voltage detector circuit
that can shut down the cpu jz4720 when monitors Battery’s voltage goes
down -VDET (2.94~3.06V) detected by BL8506-30NRM. Then this part its
detection triggers jz4720 pin123<PPRST_N> immedately. Always be nice
that many experimental data explored then to converge your this
