Note: Direction is host compared to device (card)

Notes:
1) Only required for 16-bit mode
2) Should be tied to VCC by the host.
3) If DMA operations are not used, the signal should be held high or tied to VCC by the host. For proper operation in older hosts: while DMA operations are not active, the card shall ignore this signal, including a floating condition.
