If HS1OT-V2LOW interrupt is only selected (only bit D2 set in INTR register), reading INTR register bit D2 leads to two
possibilities:
Bit D2 = 1: INT source is HS1OT.
Bit D2 = 0: INT source is V2LOW.
HS1OT and V2LOW bits status are available in IOR register.
Upon a wake up condition from stop mode due to over current detection (Idd1s-wu1 or Idd1s-wu2), an INT pulse is generated,
however INTR register content remains at 0000 (not bit set into the INTR register).
The status bit of the INT register content are a copy of the IOR and CAN registers status content. To clear the INT register bit
the IOR and/or CAN register must be cleared (read register). Once this operation is done at IOR and CAN register the INT register
is updated.
Errors bits are latched in the CAN and IOR registers.
