VSUP > VSUP_UVH on the board, FS85 calls GoTo_STBY to enter standby, wake FS85 up by WAKE1, read the value of VSUPUVH bit in M_FLAG2 is 1, which is in conflict with VSUP > VSUP_UVH, why?
In addition, in FS85, POR refers to what voltage reset.
Yes, after the system was powered on, the software cleared the VSUPUVH bit. Now keep Vsup greater than VSUP_UVH, software makes FS85 enter stanby, after Wake1 wakes IC, read VSUPUVH bit value is 1, why? To emphasize, Vsup is always greater than VSUP_UVH during this process
The Vsup on the board is always greater than VSUP_UVH, only through the software into the standby. So Vsup should not be reset. Is this understanding correct?
