ExCA power control	ExCA	802h, 842h	4, 3, 1, 0

ExCA interrupt and general control	ExCA	803h/843h	6

ExCA card status change	ExCA	804h/844h	3, 2, 1, 0

ExCA card status change interrupt	ExCA	805h/845h	3, 2, 1, 0

CardBus socket event	CardBus	00h	3, 2, 1, 0

CardBus socket mask	CardBus	04h	3, 2, 1, 0

CardBus socket status	CardBus	10h	6, 5, 4, 2, 1, 0

Global reset only bits are cleared (to default value) only when G_RST is asserted.

PME context bits are not cleared (to default value) by PRST if the PME_EN bit is set to 1.

Both G_RST and PRST can be gated by asserting the SUSPEND signal.
