Note: 1 When A side signals direction is INPUT, SD-CARD is WRITTEN by CPU-Host (i.e B side
signals direction is OUTPUT)
When A side signals direction is OUTPUT, SD-CARD is READ by CPU-Host (i.e B side
signals direction is INPUT)
2 For B side signals when Enable = L:
* Defined by internal pull-down (see Figure 3 for pins CMD.B and data bus Dat[0…3].B)
