Setting this bit to one (1), waiting the minimum reset width time
and returning to zero (0) places the card in the Reset state.
Setting this bit to “1” is equivalent to assertion of the +RESET
signal except that the SRESET bit is not cleared. Returning this
bit to “0” leaves the card in the same unconfigured Reset state
as following power-up and hardware reset. Using the PCMCIA
Soft Reset is considered a hard reset by the ATA Commands, in
contrast with Soft Reset in the Device Control Register.
This bit is set to “1” when Level Mode Interrupt is selected, and
“0” when Pulse Mode is selected. Set to “0” by reset.
Configuration Index. Set to “0” by reset. This is used to select
the card’s mode of operation as shown below. Note: Conf5 and
Conf4 are reserved and must be written as “0”.
