Register 8: Hibernation Masked Interrupt Status (HIBMIS), offset 0x01C
This register is the masked interrupt status for the Hibernation module interrupt sources. Bits in this
register are the AND of the corresponding bits in the HIBRIS and HIBIM registers. When both
corresponding bits are set, the bit in this register is set, and the interrupt is sent to the interrupt
controller.

Reset Description
RO 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.

External Wake-Up Masked Interrupt Status
Value Description
1 An unmasked interrupt was signaled due to a WAKE pin
assertion.
0 An external wake-up interrupt has not occurred or is masked.
This bit is cleared by writing a 1 to the EXTW bit in the HIBIC register.
RO
0
Low Battery Voltage Masked Interrupt Status
Value Description
1 An unmasked interrupt was signaled due to a low battery voltage
condition.
0 A low battery voltage interrupt has not occurred or is masked.
This bit is cleared by writing a 1 to the LOWBAT bit in the HIBIC register.
RO
0
RTC Alert 1 Masked Interrupt Status
Value Description
1 An unmasked interrupt was signaled due to an RTC match.
0 An RTC match interrupt has not occurred or is masked.
This bit is cleared by writing a 1 to the RTCALT1 bit in the HIBIC register.
