CONFIGURATION REGISTER
SPECIFICATION
This card supports four configuration registers for the
purpose of the configuration and observation of the card.
These registers can be used in memory card mode and I/O
card mode. In True IDE mode, these registers can not be
used.
Configuration Option Register
(Address 200h)
This register is used to configure and observe the status of
the card, and to issue soft resets to the card.
Initial Value: 00h

Function
Setting this bit to “1” places the card in the reset state. This operation is equal to a hard
reset, except this bit is not cleared.
This bit is set to “0” when pulse mode interrupt is selected, and to “1” when level mode
interupt is selected.
These bits are used to select the operation mode of the card. (See table below.) At power on,
hard reset, and soft reset, this data is “000000” for the purpose of Memory card interface
recognition, and access to CIS.
