Command Response Timings
All timing diagrams use the following schematics and abbreviations:
S: Start bit (= 0)
T: Transmitter bit (Host = 1, Card = 0)
P: One-cycle pull-up (= 1)
E: End bit (= 1)
Z: High impedance state (-> = 1)
D: Data bits
*: Repeater
CRC: Cyclic redundancy check bits (7 bits for command or response, 16 bits for block data)
The difference between the P-bit and Z-bit is that a P-bit is actively driven to HIGH by the card
respectively host output driver, while the Z-bit is driven to (respectively kept) HIGH by the pull-up
resistors R
CMD
respectively R
DAT
. Actively driven P-bits are less sensitive to noise superposition. For the
timing of these Renesas MultiMediaCards, the following values are defined:
