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.
This bit sets to “0” when pulse mode interrupt is selected, and “1” when level mode interrupt is
selected.
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.
