BAT_FAIL bit is always 0(Wakeup from LPOFF)

BAT_FAIL bit in INIT_VREG register is always 0(Even on reset), which shows that the POR never occurred. I am using debug mode. The RSTB_EXT bit in DIAG_SF_IOs register is 1 every time, I run the code.

 

Q1. Why is the BAT_FAIL bit always 0(No POR)? Even after restarting the power supply.

Q2. Why is this bit (RSTB_EXT) always 1? Does this represent the POR as well or just the external reset cases? Everytime the board starts, this bit is set. Does restart of power supply to SBC comes under reset category?

 

What can be the possibility of that behaviour of both the bits. Please let me know.

 

Thanks in advance.
