Notes:
1. The extended DAT lines (DAT1-DAT3) are input on power up. They start to operate as DAT lines
2. After power up the CD line is input with 50KOhm pull-up (can be used for card detection or SPI mode
after SET_BUS_WIDTH command. The Host shall keep its own DAT1-DAT3 lines in input mode, as
well, while they are not used. It is defined so, in order to keep compatibility to MultiMediaCards.
selection). The pull-up should be disconnected by the user, during regular data transfer, with
SET_CLR_CARD_DETECT (ACMD42) command.
