In R2 I/O Card Interface mode, this bit allows the BVD1/STSCHG#/RI# pin to be programmed as
an active-low RING indicate input. When this bit is set to ‘1’, the level on this input passes through
to the PME# output.

Sets Memory Card Interface mode. The card socket is configured to support memory-only-type cards.
All dual-function socket interface pins are defined to perform memory-only-type interface functions.
Sets I/O Card Interface mode. The card socket is configured to support combined I/O-and-memory-
type cards. All dual-function socket interface pins are defined to perform all I/O and basic memory type
interface functions.
The RESET signal to the card socket is set active (high for normal, low for ATA mode).
The RESET signal to the card socket is set inactive (low for normal, high for ATA mode).
