There is a two Z bit period followed by P bits pushed up by the responding card. The following tim-ing diagram is
relevant for all host commands followed by a response, except CMD1, CMD2 and CMD3:

Figure 7: 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.

Figure 8: Identification timing (card identification mode)
Last card response - next host command timing
After receiving the last card response, the host can start the next command transmission after at least N
RC clock cycles.
This timing is relevant for any host command.

Figure 9: Timing response end to next CMD start (data transfer mode)
Last host command - next host command timing diagram
After the last command, which does not force a response, has been sent, the host can continue sending the next
command after at least N
CC clock periods.
Figure 10: Timing CMD
n end to CMD n+1 start (all modes)
In the case the CMD
n command was a last identification command (no more response sent by a card), then the next
CMD
n+1 command is allowed to follow after at least N CC +136 (the length of the R2 response) clock periods.
