Configuration Option Register (200h in Attribute Memory)
The Configuration Option Register is used to configure the Card’s interface, address
decoding and interrupt to the Card (see Table 26).
SRESET
Setting the SRESET bit to ‘1’ and returning the bit ‘0’ places the CompactFlash Storage
Card in the Reset state. Setting this bit to ‘1’ is equivalent to asserting the RESET signal
except that the SRESET bit is not cleared. Returning the SRESET bit to ‘0’ leaves the
CompactFlash Storage Card in the same un-configured Reset state as after a power-up and
hardware reset.
This bit is set to ‘0’ at power-up and taking the Card through a hardware reset.
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) after Power Up.
Conf5 - Conf0 (Configuration Index)
These bits are used to select the operation mode of the Card as shown in Table 27. This bit
is set to ‘0’ after Power Up.
