THNCFxxxMBA/BAI Series 2002-10-20 14/48 Preliminary Configuration register specifications This card supports four Configuration registers for the purpose of the configuration and observation of this card. These registers can be used in memory card mode and I/O card mode. In True IDE mode, these registers cannot be used. 1. Configuration Option register (Address 200h) This register is used for the configuration of the card configuration status and for the issuing soft reset to the card. bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 SRESET LevIREQ INDEX Note: initial value → 00H Name R/W Function SRESET 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.
