INTR register
Control bits:
When the mask bit has been set, INTB pin goes low if the appropriate condition occurs.
Status bits:
Notes:
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.
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 contain remains at 0000 (not bit set into the INTR register).
Bit
Description
FWU
If this bit is set, and the SBC is turned into sleep or stop mode,
the SBC wakes up after the time selected in the TIM2 register
IDDS
Bit = 0: Idds-wu1 selected (lowest value, typ 3.5mA)
Bit = 1: Idds-wu2 selected (highest value, typ 14mA)
