Bits 31:16 are reserved in the CardBus Specification.
This bit is the interrupt mask. When this bit equals 0b, it masks the
modem function INTA# line but has no effect on the Modem Function
Event register. The modem function can assert the INTA# signal only
when both fields are enabled: the interrupt bit and the modem control
bit in the System Control Block (SCB) register within the CSR space.
The interrupt mask bit affects the INTA# masking only after the OS has
set this register. Thus, on legacy systems that do not access the status
change registers, the modem INTA# signal is not masked by the
interrupt.
This bit is the wake-up mask. When this bit equals 0b, it masks the
modem function CSTSCHG signal but has no effect on the Function
Event register. This bit is dependent on bit 4 of this register.
Bits 13:7 are reserved in the CardBus Specification.
These bits are used for Pulse Width Modulation Binary Audio Enable.
(PWM BAM).
This bit is the general wake-up mask. When this bit equals 0b, it masks
the modem function wake-up events towards the CSTSCHG signal. It
has no effect on the Modem Function Event register. The can assert
the CSTSCHG signal in the following configuration of masked bits:
wake-up bit AND general wake-up bit, or PME Enable bit in the
PMCSR register only.
Bit 3 is reserved in the CardBus Specification.

Bit 0 is reserved in the CardBus Specification.
Bits 31:16 are reserved in the CardBus Specification.
This bit is used for interrupts. It reflects the current state of the Modem
Interrupt (MINT) input pin from the modem.
Bits 14:5 are reserved in the CardBus Specification.
This bit is used for general wake-up. It reflects the current inverse state
of the Modem Ring (MRING#) input pin from the modem.
Bit 3 is reserved in the CardBus Specification.
