SRESET
Soft Reset - Setting this bit to one (1), waiting the minimum reset width time and returning to zero
(0) places the CompactFlash Memory Card in the Reset state. Setting this bit to one (1) is
equivalent to assertion of the +RESET signal except that the SRESET bit is not cleared.
Returning this bit to zero (0) leaves the CompactFlash Memory Card in the same un-configured,
Reset state as following power-up and hardware reset. This bit is set to zero (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.
LevlREQ
This bit is set to one (1) when Level Mode Interrupt is selected, and zero (0) when Pulse Mode is
selected. Set to zero (0) by Reset.
Conf5 - Conf0
Configuration Index. Set to zero (0) by reset. It's used to select operation mode of the
CompactFlash Memory Card as shown below.
Note:
Conf5 and Conf4 are reserved and must be written as zero (0)
