This bit allows the LED_OUT* pin to reflect any activity in the card. Whenever PCMCIA cycles
are in process to or from a card in either socket, LED_OUT* will be active low.
Bit 3: Invert Card IRQ Output
This bit changes the active-high, ISA-type card IRQ level to an active-low, open-collector output
that complies with PCI bus requirements.
Bit 4: Invert Management IRQ Output
This bit changes the active-high, ISA-type management IRQ level to an active-low, open-collector
output that complies with PCI bus requirements.
This bit turns off the pull-ups on VS2, VS1, CD2, and CD1. Turning off these pull-ups can be used
in addition to Suspend mode to even further reduce power when cards are inserted but no card
accessibility is required. Even though power may or may not still be applied, all pull-ups and their
associated inputs will be disabled.
