Function
SRESET
(HOST->)
R/W
Setting this bit to “1”, places the card in the reset state (Card Hard Reset). This
operation is equal to Hard Reset, except this bit is not cleared. Then this bit set to “0”,
places the card in the reset state of Hard Reset (This bit is set to “0” by Hard Reset) .
Card configuration status is reset and the card internal initialized operation starts when
Card Hard Reset is executed, so next access to the card should be the same sequence
as the power on sequence.
LevlREQ
(HOST->)
R/W
This bit sets to “0” when pulse mode interrupt is selected, and “1” when level mode
interrupt is selected.
INDEX
(HOST->)
R/W
This bits is used for select operation mode of the card as follows.
When Power on, Card Hard Reset and Soft Reset, this data is “000000” for the purpose
of Memory card interface recognition.
