Card relative address timings
The SD memory card timings for CMD3 (SEND_RELATIVE_ADDR) are given in
The minimum delay between the host command and the card response is N
Data transfer mode
After publishing its RCA the card switches to the data transfer mode. The command is
followed by two Z-bits (to leave time for the bus to switch direction) and then by P-bits
pushed by the responding card as shown in
Figure 20
CMD2 commands.
Last card response, next host command timings
After receiving the last card response, the host can start the next command transmission
after N
applies to any host command.
