Command Response Timing
(Identification Mode)
There is just one Z bit period followed by P bits pushed up by the responding card. The following timing
diagram is relevalent for all host commands followed by a response, except CMD1,CMD2 and CMD3 :
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 N
ID
clock cycles.
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.
Tming Response End to Next CMD Start
(Data Transfer Mode)
Last Host Command - Next Host Command Timing
After the last command has been sent, the host can continue sending the next command after at least
N
CC
clock periods.
