Register 5: Hibernation Interrupt Mask (HIBIM), offset 0x014
This register is the interrupt mask register for the Hibernation module interrupt sources. Each bit in
this register masks the corresponding bit in the Hibernation Raw Interrupt Status (HIBRIS) register.
If a bit is unmasked, the interrupt is sent to the interrupt controller. If the bit is masked, the interrupt
is not sent to the interrupt controller. The WC bit of the HIBIM register may be set before the CLK32EN
bit of the HIBCTL register is set. This allows software to use the WC interrupt trigger to detect when
the RTCOSC clock is stable, which may be in excess of one second. If the WC bit is set before the
CLK32EN has been set, the mask value is not preserved over a hibernate cycle unless the bit is
written a second time.
Note: The WC bit of this register is in the system clock domain such that a write to this bit is
immediate and may be done before the CLK32EN bit is set in the HIBCTL register.

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.
