The host command and the card response are clocked out with the rising edge of the host clock. The delay
between host command and card response is N
for host command CMD3:
There is just one Z bit period followed by P bits pushed up by the responding card. The following timing
diagram is relevant for all host commands followed by a response, except CMD1, CMD2 and CMD3:
The card identification (CMD2) and card operation condition (CMD1) timing are processed in the open-
drain mode. The card response to the host command starts after exactly N
After receiving the last card response, the host can start the next command transmission after at least N
clock cycles. This timing is relevant for any host command.
