Command Response Timing (Data Transfer Mode)
Card identification and card operation conditions timing
The card identification (CMD2) and card operation conditions (CMD1) timing are processed in the open-
drain mode. The card response to the host command starts after exactly NID clock cycles.
Identification Timing (Card Identification Mode)
