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 un ­
configured, Reset state as following power-up and hardware reset. This bit
is set to "0" by power-up and hardware reset. Using the PCMCIA Soft
Reset is considered a hard Reset by the ATA Commands. 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. It's used to select operation mode
of the card as shown below. NOTE: Conf5 and Conf4 are reserved and
must be written as "0".
