4.3 MultiMediaCard Bus Topology
The MultiMediaCard bus has three communication lines and four supply lines:
-
CMD: Command is a bi-directional signal. Host and card drivers are operating in two modes, open
drain and push pull.
-
DAT: Data is a bi-directional signal. Host and card drivers are operating in push pull mode.
-
CLK: Clock is a host to card signal. CLK operates in push pull mode.
-
VDD: VDD is the power supply line for all cards.
-
VSS[1:2]: VSS are two ground lines.

The R

is switched on and off by the host synchronously to the open-drain and push-pull mode
transitions. R
DAT
and R
CMD
are pull-up resistors protecting the CMD and the DAT line against bus
floating when no card is inserted or when all card drivers are in a hi-impedance mode. A constant
current source can replace the R
OD
by achieving a better performance (constant slopes for the signal
