Command Response Timing on MMC/SD Bus
The card identification and card operation conditions timing are processed in open-drain mode. The card
response to the host command starts after exactly NID clock cycles. For the card address assignment,
SET_RCA is also processed in the open-drain mode. The minimum delay between the host command and
card response is NCR clock cycles as illustrated in Figure 26. The symbols for Figure 26 through
Figure 30 are defined in Table 25.
