Register 7: Hibernation Raw Interrupt Status (HIBRIS), offset 0x018
This register is the raw interrupt status for the Hibernation module interrupt sources. Each bit can
be masked by clearing the corresponding bit in the HIBIM register. When a bit is masked, the
interrupt is not sent to the interrupt controller. Bits in this register are cleared by writing a 1 to the
corresponding bit in the Hibernation Interrupt Clear (HIBIC) register or by entering hibernation.

Reset Description
0x0000.000 Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
0
External Wake-Up Raw Interrupt Status
Value Description
1 The WAKE pin has been asserted.
0 The WAKE pin has not been asserted.
This bit is cleared by writing a 1 to the EXTW bit in the HIBIC register.

Low Battery Voltage Raw Interrupt Status
Value Description
1
The battery voltage dropped below VLOWBAT.
0
The battery voltage has not dropped below VLOWBAT.
This bit is cleared by writing a 1 to the LOWBAT bit in the HIBIC register.
0
RTC Alert 1 Raw Interrupt Status
Value Description
1 The value of the HIBRTCC register matches the value in the
HIBRTCM1 register.
