Third Interrupt Register
Offset: 25h
Please be aware that writing to this register will enable/disable the corresponding
interrupts, while with reading you get the actual interrupt status and will clear the
register at the same time. It is not possible to read back the interrupt enable/disable
settings. This register is reset at a DVDD-POR.

Bit Description
0
W
Real time clock supply (RVDD) under-voltage interrupt setting
0: disable
1: enable
1
RVDD_LOW
(level)
x
R
Real time clock supply interrupt reading
0: RTC supply o.k.
1: RTC supply (RVDD) was low, RTC not longer valid
The interrupt gets set in hibernation or during power-up even if
the interrupt is not enabled thus allowing to recognise a
change of the battery connected to BVDDR during hibernation
or shutdown. For a valid reading, the interrupt has to be
enabled first.
0
W
BVDD under-voltage supervisor interrupt setting
0: disable
1: enable
0
BVDD_LOW
(level)
x
R
BVDD supervisor interrupt setting
0: BVDD is above brown out level
1: BVDD has reached brown out level
The threshold can be set in the SUPERVISOR register (24h)
