CompactFlash Memory Card Interface Description
For the Attribute Memory Read function, signals -REG and -OE must be active and -WE inactive during the cycle.
As in the Main Memory Read functions, the signals -CE1 and -CE2 control the even-byte and odd-byte address, but
only the even-byte data is valid during the Attribute Memory access. Refer to Table 3-12 below for signal states and
bus validity for the Attribute Memory function.
NOTE: The -CE signal or both the -OE signal and the -WE signal must be de-asserted between consecutive cycle
3.4.2. Configuration Option Register (Address 200h in Attribute Memory)
The Configuration Option Register is used to configure the cards interface, address decoding and interrupt and to
issue a soft reset to the CompactFlash Memory Card.

SRESET
Soft Reset—Setting this bit to one (1), waiting the minimum reset width time and returning to zero (0)
This bit is set to one (1) when Level Mode Interrupt is selected, and zero (0) when Pulse Mode is selected.
Configuration Index. Set to zero (0) by reset. It's used to select operation mode of the CompactFlash
Memory Card as shown below.
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.
Set to zero (0) by Reset.
